我需要设置最大和最小 x,y 大小和矩形裁剪区域。
可能吗?如果是,该怎么做?
裁剪方法在正常使用时效果很好,但不是自定义的,它只裁剪,我不能限制裁剪大小
如何设置最小和最大裁剪尺寸?我使用的方法是:
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, 0);
int size = list.size();
if (size == 0) {
Toast.makeText(this, getApplicationContext().getString(R.string.crop_unavailable), Toast.LENGTH_SHORT).show();
// return
} else {
intent.setData(mImageCaptureUri);
int y = 200;
if(lastSelect == 1 || lastSelect == 2 || lastSelect == 3 || lastSelect == 4){
y = (int) (200 * 0.5697329376854599);
}
intent.putExtra("outputX", 200);
intent.putExtra("outputY", y);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 0.5697329376854599);
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_FROM_CAMERA);
} else {
for (ResolveInfo res: list) {
final CropOption co = new CropOption();
co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(getApplicationContext().getString(R.string.select_crop_app));
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
startActivityForResult(cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
if (mImageCaptureUri != null) {
getContentResolver().delete(mImageCaptureUri, null, null);
mImageCaptureUri = null;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
}
