仿微信通过拍照、本地图片然后裁剪完美更换头像
其实更换头像这个功能是个老梗了，写的人也很多，但是我没有看见过特别让我满意的，没办法，只能自己搞了。这里面我只说难点吧，最后的会附上完整的代码。
这里面涉及到的功能有哪些呢？
大概有：拍照 、扫描本地图片、裁剪、可以拖动放大缩小的图片、圆形头像，自认为还是比较不错的，代码风格可能能有改进，大家可以自行修改！~
一、首页main.activity
public class MainActivity extends AppCompatActivity {
private CircleImageView headerP
private TextView textV
private static final String IMAGE_FILE_LOCATION = ConstantSet.LOCALFILE;
Uri imageU
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
headerPic=(CircleImageView)findViewById(R.id.headerImage);
textView=(TextView)findViewById(R.id.updateImages);
textView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
View uv = getLayoutInflater().from(MainActivity.this).inflate(R.layout.upload_user_pic, null);
TextView photograph = (TextView) uv.findViewById(R.id.Photograph);
TextView selectPic = (TextView) uv.findViewById(R.id.selectImage_from_local);
TextView dimissDialoag = (TextView) uv.findViewById(R.id.dimiss_dialoag);
builder.setView(uv);
final AlertDialog alertDialog = builder.show();
MyDialoagListener myDialoagListener = new MyDialoagListener(alertDialog);
photograph.setOnClickListener(myDialoagListener);
selectPic.setOnClickListener(myDialoagListener);
dimissDialoag.setOnClickListener(myDialoagListener);
file = new File(IMAGE_FILE_LOCATION);
if(!file.exists()){
SDCardUtils.makeRootDirectory(IMAGE_FILE_LOCATION);
file=new File(IMAGE_FILE_LOCATION+ConstantSet.USERTEMPPIC);
imageUri = Uri.fromFile(file);
* 头像更改监听
private class MyDialoagListener implements View.OnClickListener {
private AlertDialog alertD
public MyDialoagListener(AlertDialog alertDialog) {
this.alertDialog = alertD
public void onClick(View v) {
switch (v.getId()) {
case R.id.Photograph:
alertDialog.dismiss();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, ConstantSet.TAKEPICTURE);
case R.id.selectImage_from_local:
Intent sintent = new Intent(MainActivity.this, SelectImagesFromLocalActivity.class);
startActivityForResult(sintent, ConstantSet.SELECTPICTURE);
alertDialog.dismiss();
case R.id.dimiss_dialoag:
alertDialog.dismiss();
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
switch (requestCode) {
case ConstantSet.TAKEPICTURE:
Intent tcutIntent = new Intent(MainActivity.this, ClippingPageActivity.class);
tcutIntent.putExtra("type", "takePicture");
startActivityForResult(tcutIntent, ConstantSet.CROPPICTURE);
case ConstantSet.SELECTPICTURE:
Intent scutIntent = new Intent(MainActivity.this, ClippingPageActivity.class);
scutIntent.putExtra("type", "selectPicture");
scutIntent.putExtra("path",data.getStringExtra("path"));
startActivityForResult(scutIntent, ConstantSet.CROPPICTURE);
case ConstantSet.CROPPICTURE:
byte[] bis = data.getByteArrayExtra("result");
Bitmap bitmap = BitmapFactory.decodeByteArray(bis, 0, bis.length);
headerPic.setImageBitmap(bitmap);
首页效果大致就是这个样子：
二、SelectImagesFromLocalActivity
public class SelectImagesFromLocalActivity extends AppCompatActivity implements
View.OnClickListener,ImagesFolderPopupWindow.FinishOnItemClickListener,AdapterView.OnItemClickListener {
private DisplayImageOptions options = null;
private GridView mgridV
private SpinnerProgressD
private LinearLayout mSelectI
private TextView mFolderN
private ImageGridViewA
private ImagesFolderPopupW
private ArrayList&ImageBean& marrayList=new ArrayList&&();
private ArrayList&ImageFolderBean& arrayList=new ArrayList&&();
private HashMap&String,ArrayList&ImageBean&&
mgroupMap=new HashMap&&();
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_from_local);
msp=new SpinnerProgressDialoag(this);
initTitle();
mgridView=(GridView)findViewById(R.id.imagesGridView);
mgridView.setOnItemClickListener(this);
mSelectImages=(LinearLayout)findViewById(R.id.selectImagesFromFolder);
mSelectImages.setOnClickListener(this);
mFolderName=(TextView)findViewById(R.id.imagesFolderName);
initImageLoader();
madapter=new ImageGridViewAdapter(this,options);
mgridView.setAdapter(madapter);
pop=new ImagesFolderPopupWindow(this,options);
pop.setFinishOnItemClickListener(this);
new RequestLocalImages().execute();
private void initTitle() {
ImageView rightImage = (ImageView) findViewById(R.id.id_img_right);
TextView title = (TextView) findViewById(R.id.id_title);
ImageView back = (ImageView) findViewById(R.id.id_back);
rightImage.setVisibility(View.GONE);
title.setText(getResources().getString(R.string.images));
back.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
SelectImagesFromLocalActivity.this.finish();
public void onItemClick(AdapterView&?& parent, View view, int position, long id) {
ImageBean imageBean=(ImageBean)parent.getItemAtPosition(position);
String path=imageBean.getImagePath();
File file=new File(path);
if(file.exists()) {
Intent itToClip = new Intent();
itToClip.putExtra("path", path);
setResult(RESULT_OK, itToClip);
this.finish();
public void onClick(View v) {
switch (v.getId()){
case R.id.selectImagesFromFolder:
pop.showPopupWindow(v);
public void OnFinishedClick(String name) {
madapter.setArrayList(mgroupMap.get(name));
mFolderName.setText(name);
private class
RequestLocalImages extends AsyncTask&String,Integer,String&{
public RequestLocalImages() {
protected String doInBackground(String... params) {
Cursor imageCursor = getContentResolver().
query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[]{MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID},
null, null, MediaStore.Images.Media._ID);
mgroupMap.put(getResources().getString(R.string.all_images),marrayList);
if (imageCursor != null && imageCursor.getCount() & 0) {
while (imageCursor.moveToNext()) {
ImageBean item = new ImageBean(imageCursor.
getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA)));
mgroupMap.get(getResources().getString(R.string.all_images)).add(item);
String parentPath=new File(item.getImagePath()).getParentFile().getName();
if(!mgroupMap.containsKey(parentPath)){
ArrayList&ImageBean& arrayList=new ArrayList&&();
arrayList.add(item);
mgroupMap.put(parentPath,arrayList);
mgroupMap.get(parentPath).add(item);
subGroupOfImage(mgroupMap);
return null;
protected void onPostExecute(String s) {
madapter.setArrayList(mgroupMap.get(getResources().getString(R.string.all_images)));
pop.setArrayList(arrayList);
super.onPostExecute(s);
private void subGroupOfImage(HashMap&String,ArrayList&ImageBean&&
mgroupMap){
if(mgroupMap==null||mgroupMap.size()==0){
Iterator&Map.Entry&String,ArrayList&ImageBean&&& iterator=mgroupMap.entrySet().iterator();
while (iterator.hasNext()){
Map.Entry&String,ArrayList&ImageBean&& entry=iterator.next();
ImageFolderBean ifb=new ImageFolderBean();
ifb.setFirstImage(entry.getValue().get(0).getImagePath());
ifb.setFolderName(entry.getKey());
ifb.setImages(entry.getValue().size());
if(!entry.getKey().equals(getResources().getString(R.string.all_images))){
ifb.setIsSelected(false);
arrayList.add(ifb);
ifb.setIsSelected(true);
arrayList.add(0,ifb);
private void initImageLoader() {
if (options == null) {
DisplayImageOptions.Builder displayBuilder = new DisplayImageOptions.Builder();
displayBuilder.cacheInMemory(true);
displayBuilder.cacheOnDisk(true);
displayBuilder.showImageOnLoading(R.mipmap.default_photo);
displayBuilder.showImageForEmptyUri(R.mipmap.default_photo);
displayBuilder.considerExifParams(true);
displayBuilder.bitmapConfig(Bitmap.Config.RGB_565);
displayBuilder.imageScaleType(ImageScaleType.EXACTLY);
displayBuilder.displayer(new FadeInBitmapDisplayer(300));
options = displayBuilder.build();
if (!ImageLoader.getInstance().isInited()) {
ImageLoaderConfiguration.Builder loaderBuilder = new ImageLoaderConfiguration.Builder(getApplication());
loaderBuilder.memoryCacheSize(getMemoryCacheSize());
File cacheDir = new File(getExternalCacheDir() + File.separator + ConstantSet.IMAGE_CACHE_DIRECTORY);
loaderBuilder.diskCache(new LruDiskCache(cacheDir, DefaultConfigurationFactory.createFileNameGenerator(), 500 * 1024 * 1024));
} catch (IOException e) {
e.printStackTrace();
ImageLoader.getInstance().init(loaderBuilder.build());
private int getMemoryCacheSize() {
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
int screenWidth = displayMetrics.widthP
int screenHeight = displayMetrics.heightP
return screenWidth * screenHeight * 4 * 3;
效果如图所示：
三、裁剪中最重要的可以拖动、缩放的imageView，当然很多代码网上都有，只不过我稍加改动
PerfectControlImageView
public class PerfectControlImageView extends ImageView {
float x_down = 0;
float y_down = 0;
PointF start = new PointF();
PointF mid = new PointF();
float oldDist = 1f;
float oldRotation = 0;
Matrix matrix = new Matrix();
Matrix matrix1 = new Matrix();
Matrix savedMatrix = new Matrix();
private static final int NONE = 0;
private static final int DRAG = 1;
private static final int ZOOM = 2;
int mode = NONE;
boolean matrixCheck = false;
int widthS
int heightS
private int titleH
public PerfectControlImageView(Context context) {
this(context, null);
public PerfectControlImageView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
TypedArray typedArray=context.obtainStyledAttributes
(attrs, R.styleable.PerfectControlImageView,defStyleAttr,0);
titleHeight=typedArray.getDimensionPixelSize(R.styleable.PerfectControlImageView_titleHeight,
(int)TypedValue.PLEX_UNIT_DIP,59,getResources().getDisplayMetrics()));
widthScreen= ScreenUtils.getScreenWidth(context);
heightScreen=ScreenUtils.getScreenHeight(context)-
ScreenUtils.getStatusHeight(context)-
matrix = new Matrix();
public PerfectControlImageView(Context context, AttributeSet attrs) {
this(context, attrs,0);
public void setImageBitmap(Bitmap bm) {
this.gintama=
matrix.postTranslate((widthScreen-gintama.getWidth())/2,(heightScreen-gintama.getHeight())/2);
protected void onDraw(Canvas canvas) {
canvas.save();
canvas.drawBitmap(gintama, matrix, null);
canvas.restore();
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_DOWN:
mode = DRAG;
x_down = event.getX();
y_down = event.getY();
savedMatrix.set(matrix);
case MotionEvent.ACTION_POINTER_DOWN:
mode = ZOOM;
oldDist = spacing(event);
savedMatrix.set(matrix);
midPoint(mid, event);
case MotionEvent.ACTION_MOVE:
if (mode == ZOOM) {
matrix1.set(savedMatrix);
float newDist = spacing(event);
float scale = newDist / oldD
matrix1.postScale(scale, scale, mid.x, mid.y);
matrixCheck = matrixCheck();
if (matrixCheck == false) {
matrix.set(matrix1);
invalidate();
} else if (mode == DRAG) {
matrix1.set(savedMatrix);
matrix1.postTranslate(event.getX() - x_down, event.getY()
- y_down);
matrixCheck = matrixCheck();
matrixCheck = matrixCheck();
if (matrixCheck == false) {
matrix.set(matrix1);
invalidate();
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_POINTER_UP:
mode = NONE;
return true;
private boolean matrixCheck() {
float[] f = new float[9];
matrix1.getValues(f);
float x1 = f[0] * 0 + f[1] * 0 + f[2];
float y1 = f[3] * 0 + f[4] * 0 + f[5];
float x2 = f[0] * gintama.getWidth() + f[1] * 0 + f[2];
float y2 = f[3] * gintama.getWidth() + f[4] * 0 + f[5];
float x3 = f[0] * 0 + f[1] * gintama.getHeight() + f[2];
float y3 = f[3] * 0 + f[4] * gintama.getHeight() + f[5];
float x4 = f[0] * gintama.getWidth() + f[1] * gintama.getHeight() + f[2];
float y4 = f[3] * gintama.getWidth() + f[4] * gintama.getHeight() + f[5];
double width = Math.sqrt((x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2));
if (width & widthScreen / 3 || width & widthScreen * 3) {
return true;
if ((x1 & widthScreen / 3 && x2 & widthScreen / 3
&& x3 & widthScreen / 3 && x4 & widthScreen / 3)
|| (x1 & widthScreen * 2 / 3 && x2 & widthScreen * 2 / 3
&& x3 & widthScreen * 2 / 3 && x4 & widthScreen * 2 / 3)
|| (y1 & heightScreen / 3 && y2 & heightScreen / 3
&& y3 & heightScreen / 3 && y4 & heightScreen / 3)
|| (y1 & heightScreen * 2 / 3 && y2 & heightScreen * 2 / 3
&& y3 & heightScreen * 2 / 3 && y4 & heightScreen * 2 / 3)) {
return true;
return false;
private float spacing(MotionEvent event) {
float x = event.getX(0) - event.getX(1);
float y = event.getY(0) - event.getY(1);
return (float)Math.sqrt(x * x + y * y);
private void midPoint(PointF point, MotionEvent event) {
float x = event.getX(0) + event.getX(1);
float y = event.getY(0) + event.getY(1);
point.set(x / 2, y / 2);
private float rotation(MotionEvent event) {
double delta_x = (event.getX(0) - event.getX(1));
double delta_y = (event.getY(0) - event.getY(1));
double radians = Math.atan2(delta_y, delta_x);
return (float) Math.toDegrees(radians);
public Bitmap CreatNewPhoto() {
Bitmap bitmap = Bitmap.createBitmap(widthScreen, heightScreen,
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
canvas.drawBitmap(gintama, matrix, null);
canvas.save(Canvas.ALL_SAVE_FLAG);
canvas.restore();
四、ClippingPageActivity
public class ClippingPageActivity extends AppCompatActivity {
private PerfectControlImageView imageV
private CuttingFrameView cuttingFrameV
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_clipping_page);
initTitle();
cuttingFrameView = (CuttingFrameView) findViewById(R.id.cutingFrame);
imageView = (PerfectControlImageView) findViewById(R.id.targetImage);
if (getIntent().getStringExtra("type").equals("takePicture")) {
bitmap = BitmapUtils.DecodLocalFileImage(ConstantSet.LOCALFILE + ConstantSet.USERTEMPPIC, this);
String path=getIntent().getStringExtra("path");
bitmap = BitmapUtils.DecodLocalFileImage(path, this);
if (bitmap != null) {
imageView.setImageBitmap(bitmap);
* 初始化title
private void initTitle() {
ImageView rightImage = (ImageView) findViewById(R.id.id_img_right);
TextView title = (TextView) findViewById(R.id.id_title);
TextView righttext=(TextView)findViewById(R.id.id_text_right);
ImageView back = (ImageView) findViewById(R.id.id_back);
rightImage.setVisibility(View.GONE);
righttext.setVisibility(View.VISIBLE);
title.setText(getResources().getString(R.string.picture_cutting));
back.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
ClippingPageActivity.this.finish();
righttext.setText(getResources().getString(R.string.sure));
righttext.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
SpinnerProgressDialoag sp=new SpinnerProgressDialoag(ClippingPageActivity.this);
sp.show();
Bitmap bitmap=cuttingFrameView.takeScreenShot(ClippingPageActivity.this);
SDCardUtils.saveMyBitmap(ConstantSet.LOCALFILE, ConstantSet.USERPIC, bitmap);
Intent it=new Intent();
ByteArrayOutputStream baos=new ByteArrayOutputStream();
pressFormat.JPEG, 100, baos);
byte [] bitmapByte =baos.toByteArray();
it.putExtra("result", bitmapByte);
setResult(RESULT_OK, it);
sp.dismiss();
ClippingPageActivity.this.finish();
