请尝试这个方法,我知道现在可能有点晚了,但可能会对某些人有帮助。
private void performCrop() {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(mImageCaptureUri, "image/*");
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", 4);
cropIntent.putExtra("aspectY", 3);
cropIntent.putExtra("outputX", 800);
cropIntent.putExtra("outputY", 800);
File f = new File(Environment.getExternalStorageDirectory(),
"/temporary_holder.jpg");
try {
f.createNewFile();
} catch (IOException ex) {
Log.e("io", ex.getMessage());
}
uri = Uri.fromFile(f);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(cropIntent, PIC_CROP);
}
catch (ActivityNotFoundException anfe) {
String errorMessage = "Your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
将您的onActivityResult修改为如下所示:-
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PIC_CROP) {
String filePath = Environment.getExternalStorageDirectory()
+ "/temporary_holder.jpg";
thumbnail = BitmapFactory.decodeFile(filePath);
ImageView image = (ImageView) findViewById(R.id.pestImage);
image.setImageBitmap(thumbnail);
}
}
