我正在尝试在我的Android平板电脑中裁剪,但它无法正常工作。
我使用的是Nexus 10。
嗯......这是我的裁剪代码:
private void doCrop(){
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(mImageCaptureUri, "image/*");
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
if (size == 0) {
Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(mImageCaptureUri);
intent.putExtra("outputX", 648);
intent.putExtra("outputY", 486);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROP_RESULT);
} else {
}
}
}
这是我的对话框,要求&#34;相机&#34;或&#34;图库&#34;:
private void startDialog() {
AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
myAlertDialog.setTitle("Selecione uma foto!");
myAlertDialog.setMessage("Choose a source");
myAlertDialog.setPositiveButton("Gallery", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
pictureActionIntent = new Intent(Intent.ACTION_GET_CONTENT, null);
pictureActionIntent.setType("image/*");
pictureActionIntent.putExtra("return-data", true);
startActivityForResult(pictureActionIntent, GALLERY_PICTURE);
}
});
myAlertDialog.setNegativeButton("Camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
pictureActionIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
storagePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/tmp/android.jpg";
pictureActionIntent.putExtra(MediaStore.EXTRA_OUTPUT, storagePath);
startActivityForResult(pictureActionIntent, CAMERA_PICTURE);
}
});
myAlertDialog.show();
}
这是我的onActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap bmp;
if (resultCode == RESULT_OK){
switch (requestCode){
case GALLERY_PICTURE :
mImageCaptureUri = data.getData();
doCrop();
break;
case CROP_RESULT :
Bundle extras = data.getExtras();
if (extras != null) {
bmp = extras.getParcelable("data");
bmp = Bitmap.createScaledBitmap(bmp, 648, 486, true);
Drawable d = new BitmapDrawable(getResources(),bmp);
btnTitular.setCompoundDrawablesWithIntrinsicBounds(null, d, null, null);
}
File f = new File(mImageCaptureUri.getPath());
if (f.exists()) f.delete();
Intent inten3 = new Intent(this, CadTitularActivity.class);
startActivity(inten3);
break;
case CAMERA_PICTURE :
doCrop();
break;
}
}
}
以下是发生的事情:
当我从图库中抓取图像时,裁剪显示但是当我点击&#34;确定&#34;要裁剪图像,它什么都不做。
当我从相机中抓取图片时,它什么也没做。它只显示&#34;正在加载图片&#34;没有任何反应。
任何想法?
请记住:我使用的是Nexus 10.我已经听说过这种裁剪对所有设备都不起作用。
欢迎任何帮助!
谢谢!
答案 0 :(得分:-1)
我认为问题是输出x和y必须将裁剪意图设置为256 x 256(或更小)。
所以改变代码:
intent.putExtra("outputX", 648);
intent.putExtra("outputY", 486);
到此:
intent.putExtra("outputX", 256);
intent.putExtra("outputY", 256);
它应该适合你。
