当相机活动返回时，承载这个片段的活动有它的onActivityResult被调用。
我的片段开始一个活动的结果与意图发送给相机拍照。图片应用程序加载正常，拍摄照片并返回。然而onActivityResult从未被击中。我设置了断点，但什么都没有触发。一个片段可以有onActivityResult吗?我想是的，因为它是一个已提供的函数。为什么这个没有被触发?
ImageView myImage = (ImageView)inflatedView.findViewById(R.id.image);
myImage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1888);
}
});
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if( requestCode == 1888 ) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
((ImageView)inflatedView.findViewById(R.id.image)).setImageBitmap(photo);
}
}
我在使用ChildFragmentManager时有同样的问题。管理器不会将结果传递给嵌套片段，您必须在基本片段中手动执行此操作。
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
Fragment fragment = (Fragment) getChildFragmentManager().findFragmentByTag(childTag);
if (fragment != null) {
fragment.onActivityResult(requestCode, resultCode, intent);
}
}
最简单的方法之一是从你的片段开始一个活动。
startActivity(ActivityName);
然后，添加你调用startActivityForResult(intent，"1");在你的Activity中添加onActivityResult
startActivityForResult(intent,"1");
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.dualPane);
fragment.onActivityResult(requestCode, resultCode, data);
// perform other activity result like fetching from Uris or handling cursors
finish(); // finish the activity will get to back to your fragment.
}
You can simply override BaseActivity onActivityResult on fragment baseActivity.startActivityForResult .
On BaseActivity add interface and override onActivityResult.
private OnBaseActivityResult baseActivityResult;
public static final int BASE_RESULT_RCODE = 111;
public interface OnBaseActivityResult{
void onBaseActivityResult(int requestCode, int resultCode, Intent data);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(getBaseActivityResult() !=null && requestCode == BASE_RESULT_RCODE){
getBaseActivityResult().onBaseActivityResult(requestCode, resultCode, data);
setBaseActivityResult(null);
}
On Fragment implements OnBaseActivityResult
@Override
public void onBaseActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("RQ","OnBaseActivityResult");
if (data != null) {
Log.d("RQ","OnBaseActivityResult + Data");
Bundle arguments = data.getExtras();
}
}
这个变通方法会奏效。
我只是做了一个变通方法:
public static Fragment _tempFragment = null;
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(_tempFragment != null)
_tempFragment.onActivityResult(requestCode, resultCode, data);
}
在Fragment中，在startActivityResult之前，设置
MainActivity._tempFragment = this;
在片段中的onActivityResult <——之后
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Do your job
{
}
MainActivity._tempFragment = null;
}
