setOnItemClickListener() 在片段中的 gridView 上不起作用

Question

setOnItemClickListener(( 在 gridFragment 中不起作用

我在片段中有一个网格视图，我为此设置了一个项目单击，但是它不起作用

我已经尝试过android:descendantFocusability="blocksDescendants"但仍然没有点击

这是代码

public class ImageGalfrag extends Fragment {
private Cursor cursor;
private int columnIndex;
ImageView thumbV;
ImageButton videoICON;
ArrayList<Bitmap> bitmapArray = new ArrayList<Bitmap>();
//   @Override
//    public void onCreate(Bundle savedInstanceState) {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.gallery_gridview, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//setContentView(R.layout.gallery_gridview);
try {
String[] projection = {MediaStore.Images.Thumbnails._ID};
cursor = getActivity().managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null,       // Return all rows
null,
MediaStore.Images.Thumbnails.IMAGE_ID);
View v = getView();
// Get the column index of the Thumbnails Image ID
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
GridView sdcardImages = (GridView) v.findViewById(R.id.PhoneImageGrid);
sdcardImages.setAdapter(new ImageAdapter(getActivity()));
sdcardImages.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
String[] projection = {MediaStore.Images.Media.DATA};
cursor = getActivity().managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null,       // Return all rows
null,
null);
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToPosition(position);
String imagePath = cursor.getString(columnIndex);
Toast.makeText(getActivity(), "" + imagePath, Toast.LENGTH_SHORT).show();
ImageAdd(imagePath);
Intent ImageIntent = new Intent(getActivity(), ZoomImageView.class);
ImageIntent.putExtra("ImageName", imagePath);
getActivity().startActivity(ImageIntent);
}
});
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
}
public void ImageAdd(String imagePath){
try {
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
Bitmap bitmap = BitmapFactory.decodeFile(imagePath, bmOptions);
bitmapArray.add(bitmap);
} catch (Exception e) {
e.printStackTrace();
}
}
private class ImageAdapter extends BaseAdapter {
private Context context;
public ImageAdapter(Context localContext) {
context = localContext;
}
public int getCount() {
return cursor.getCount();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
View grid = null;
try {
LayoutInflater inflater = getActivity().getLayoutInflater();
if (convertView == null) {
try {
cursor.moveToPosition(position);
int imageID = cursor.getInt(columnIndex);
//grid = new View(mContext);
grid = inflater.inflate(R.layout.gallery_view, null);
//TextView textView = (TextView) grid.findViewById(R.id.grid_text);
thumbV = (ImageView) grid.findViewById(R.id.thumbImage);
thumbV.setImageURI(Uri.withAppendedPath(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID));
videoICON = (ImageButton) grid.findViewById(R.id.videoICON);
//textView.setText("");
} catch (Exception e) {
e.printStackTrace();
}
} else {
grid = (View) convertView;
}
} catch (Exception e) {
e.printStackTrace();
}
return grid;
}
}
}

布局是

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants"
>
<GridView
android:id="@+id/PhoneImageGrid"
android:numColumns="2"
android:gravity="center"
android:columnWidth="250dp"
android:stretchMode="columnWidth"
android:layout_width="fill_parent"
android:layout_height="wrap_content"></GridView>
</RelativeLayout>

网格项是

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragment_gallery1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:orientation="vertical"
android:padding="5dp">
<LinearLayout
android:id="@+id/fragment_gallery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#455569"
android:orientation="vertical"
android:padding="5dp">
<ImageView
android:id="@+id/thumbImage"
android:layout_width="match_parent"
android:layout_height="150dp"
android:layout_gravity="center_horizontal"
android:background="#CCCCCC"
android:scaleType="fitXY"
android:layout_margin="5dp"
android:src="@mipmap/ic_launcher" />
<ImageButton
android:id="@+id/videoICON"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_below="@+id/thumbImage"
android:layout_gravity="center_horizontal"
android:layout_marginTop="0dp"
android:background="#00000000"
android:scaleType="fitXY" />
</LinearLayout>
</LinearLayout>

不要使用ItemClickListener。

在您的getView()方法中，在您的适配器中。这样做：

@Override
public View getView(final int position ...
grid.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Do something
}});
