我正在尝试对每个片段中捕获的图像进行图像视图，但似乎在捕获图像时，预览每次都显示在第一个片段中，这是我的代码：
public static class TestFragment extends Fragment {
int mNum;
String s;
/**
* * Create a new instance of CountingFragment, providing "num" * as an
* argument.
*/
public static TestFragment newInstance(int position) {
// Log.i("Pager", "TestFragment.newInstance()");
TestFragment fragment = new TestFragment();
Bundle args = new Bundle();
args.putInt("position", position);
args.putString("s", array[position]);
fragment.setArguments(args);
return fragment;
}
/** * When creating, retrieve this instance's number from its arguments. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mNum = getArguments() != null ? getArguments().getInt("position")
: 1;
s=getArguments() != null ? getArguments().getString("s")
: "";
}
/**
* * The Fragment's UI is just a simple text view showing its instance
* number.
*/
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View layout = inflater.inflate(R.layout.add_read_meter, null);
int position = getArguments().getInt("position");
TextView tv = (TextView) layout.findViewById(R.id.clientNameId);
tv.setText("Fragment #" + mNum+" :"+s);
// iv=(ImageView)layout.findViewById(R.id.imagev);
Button b2 = (Button) layout.findViewById(R.id.imagBtnId);
b2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Uri _fileUri = getOutputMediaFile();
myUri = _fileUri;
// Log.i(TAG, myUri.toString());
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, _fileUri);
getActivity().startActivityForResult(intent,
CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
});
return layout;
}
这是 onActivityResult 方法：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE
&& resultCode == Activity.RESULT_OK) {
TestFragment myFragment = (TestFragment)
getSupportFragmentManager().findFragmentById(R.id.pager);
myFragment.getId();
Bitmap bitmap;
if (myUri != null) {
try {
bitmap = MediaStore.Images.Media.getBitmap(
this.getContentResolver(), myUri);
// Bitmap photo = (Bitmap) data.getExtras().get("data");
ImageView iv = (ImageView) findViewById(R.id.imagev);
iv.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
super.onActivityResult(requestCode, resultCode, data);
Toast.makeText(FragmentPagerSupport.this, myUri.toString(),
Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
