В моем приложении я использовал Custom Gridview для отображения изображения с текстом, но при этом, когда я нажимаю на конкретный элемент сетки, используя setOnItemClick (...), он не может быть вызван мой вид сетки в XML-файле Подписчиков,Android GridView setOnItemClick (...) не может быть вызван
<GridView
android:id="@+id/gridview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:columnWidth="100dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
и в моем файле активности Java,
gridView = (GridView) findViewById(R.id.gridview);
customGridAdapter = new GridViewAdapter(this, R.layout.row_grid,
getData());
gridView.setAdapter(customGridAdapter);
System.out.println("call start");
gridView.setOnItemClickListener(new OnItemClickListener() { // it not call
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(GridCameraPreviewTestActivity.this,
position + "Selected", Toast.LENGTH_SHORT).show();
System.out.println("on grid click");
}
}
}
});
EDIT:
мой row_gr id.xml Подписчики,
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:orientation="vertical"
android:padding="5dp"
android:clickable="true"
android:background="@drawable/grid_color_selector"
android:focusable="true"
>
<ImageView
android:id="@+id/image"
android:layout_width="100dp"
android:layout_height="100dp" >
</ImageView>
<TextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"

</TextView>
</LinearLayout>
EDIT 2:
мое Целое GridCameraPreviewTestActivity следующие:
public class GridCameraPreviewTestActivity extends Activity implements
AdapterView.OnItemSelectedListener, OnClickListener,
OnItemClickListener {
private ResizableCameraPreview mPreview;
private ArrayAdapter<String> mAdapter;
private RelativeLayout mLayout;

@Override

super.onCreate(savedInstanceState);

mAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item);
mAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerSize.setAdapter(mAdapter);
spinnerSize.setOnItemSelectedListener(this);
// Spinner for camera ID
Spinner spinnerCamera = (Spinner) findViewById(R.id.spinner_camera);
ArrayAdapter<String> adapter;
adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinnerCamera.setAdapter(adapter);
spinnerCamera.setOnItemSelectedListener(this);
adapter.add("0");
adapter.add("1");
adapter.add("2");
mLayout = (RelativeLayout) findViewById(R.id.layout);
// start
gridView = (GridView) findViewById(R.id.gridview);

}
});
System.out.println("call over");
}
@Override

long id) {
Log.w("CameraPreviewTestActivity", "onItemSelected invoked");
Log.w("CameraPreviewTestActivity", "position: " + position);
Log.w("CameraPreviewTestActivity", "parent.getId(): " + parent.getId());
switch (parent.getId()) {
case R.id.spinner_size:

mLayout.getDrawingRect(rect);
if (0 == position) { // "Auto" selected
mPreview.surfaceChanged(null, 0, rect.width(), rect.height());
} else {

}
break;
case R.id.spinner_camera:

mLayout.removeView(mPreview);
mCameraId = position;
createCameraPreview();
break;
}
}
@Override

// do nothing
}
@Override

}
@Override

super.onPause();
mPreview.stop();
mLayout.removeView(mPreview);
mPreview = null;
}
private void createCameraPreview() {
// Set the second argument by your choice.
// Usually, 0 for back-facing camera, 1 for front-facing camera.
// If the OS is pre-gingerbreak, this does not have any effect.
mPreview = new ResizableCameraPreview(this, mCameraId,
CameraPreview.LayoutMode.FitToParent, false);
LayoutParams previewLayoutParams = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
mLayout.addView(mPreview, 0, previewLayoutParams);
mAdapter.clear();
mAdapter.add("Auto");
List<Camera.Size> sizes = mPreview.getSupportedPreivewSizes();
for (Camera.Size size : sizes) {
mAdapter.add(size.width + " x " + size.height);
}
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
private ArrayList<ImageItem> getData() {
// other code here
}
return imageItems;
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
}
}
любого помочь мне решить эту проблему, спасибо в продвинутых.
пост 'row_grid' макет – kId
увидеть мой файл row_grix.xml –
есть вы определили View.onClickListener() в адаптеры просмотра у Вас кал либо вызывать OnClick на просмотр адаптера или setOnItemClickListener –
