解决图片裁剪com.android.camera.action.CROP和intent.putExtra("return-data", true);

  最近在做一个图片上传,在上传之前需要对照片进行裁剪,遇到一个坑,在别的手机上运行都正常,在小米手机上却遇见一个问题,选中图片无法裁剪,直接闪退,目前已解决!之前出过问题的地方会标红 

 

 //选择图片

  private void choosePhotos(){

    Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*");
    startActivityForResult(intent, CHOOSE_PICTURE);

  }

 

  @Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
      switch (requestCode) {
        case CHOOSE_PICTURE:
          // 对图片进行裁剪处理
          cutImage(data.getData());
          break;
        case CROP_SMALL_PICTURE:
          if (data != null) {
            try {
              Bitmap head=BitmapFactory.decodeStream(getContentResolver().openInputStream(uritempFile));
              // 让刚才选择裁剪得到的图片显示在界面上
              setImageView (head);
            } catch (FileNotFoundException e) {
              e.printStackTrace();
            }
          }
          break;
      }
  }

 

  

  // 对图片进行裁剪处理
  protected void cutImage(Uri uri) {
    //com.android.camera.action.CROP这个action是用来裁剪图片用的
    Intent intent = new Intent("com.android.camera.action.CROP");
    intent.setDataAndType(uri, "image/*");
    // 设置裁剪
    intent.putExtra("crop", "true");
    // aspectX aspectY 是宽高的比例
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    // outputX outputY 是裁剪图片宽高
    intent.putExtra("outputX", 150);
    intent.putExtra("outputY", 150);

    //这里不用return-data返回(稍后解释)
    //intent.putExtra("return-data", true);

    uritempFile = Uri.parse("file://" + "/" + Environment.getExternalStorageDirectory().getPath() + "/" + "temp_image.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT, uritempFile);
    intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());

    startActivityForResult(intent, CROP_SMALL_PICTURE);
  }

 

  

  //图片回显
  private void setImageView (Bitmap bitmap){
    Bitmap bitmap_bg=Bitmap.createBitmap(bitmap.getWidth(),bitmap.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas=new Canvas(bitmap_bg);
    Paint paint = new Paint();
    paint.setAntiAlias(true);
    paint.setColor(Color.GREEN);
    //这里使用了绘图的模式的功能,PorterDuff.Mode.SRC_IN表示两个图层显示重合部分上面图层的内容
    canvas.drawOval(new RectF(0,0,bitmap.getWidth(),bitmap.getHeight()),paint);
    paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
    canvas.drawBitmap(bitmap,0,0,paint);
    Drawable drawable =new BitmapDrawable(bitmap_bg);
    //personImage是需要赋值的id
    image.setImageDrawable(drawable);
  }

 

  OK!从照片库选择裁剪并且上传就成功了!

  若是截取小图可以直接  intent.putExtra("return-data", true);

  若是大图可将图片直接转成uri进行传递
