android自定义gridview实现中的子项click listner

Question

我有自定义适配器实现的网格视图。触摸网格视图项时，将选择整个项。我想对在网格视图中选择不同的子项执行不同的操作。

在下面的例子中，我在项目中有两个图像和一个文本视图。我想在触摸文本视图、图像视图时执行不同的操作。

这是可能做到这一点在Android？

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listrow"
android:layout_width="fill_parent"
android:layout_height="66dp"
android:background="@drawable/grid_color_selector"
android:descendantFocusability="blocksDescendants"
android:focusable="false"
android:focusableInTouchMode="false"
android:gravity="fill_horizontal" >

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:focusable="false"
    android:focusableInTouchMode="false"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/thumbimage"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_margin="4dp"
        android:layout_weight="1"
        android:clickable="false"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:scaleType="fitXY"
        android:src="@drawable/icon" />

    <TextView
        android:id="@+id/txttitle"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:layout_marginTop="10dp"
        android:layout_weight="44"
        android:clickable="false"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:text="English Channels"
        android:textColor="@color/Black"
        android:textSize="16sp" />

    <ImageView
        android:id="@+id/share"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_margin="4dp"
        android:layout_weight="1"
        android:clickable="false"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:scaleType="fitXY"
        android:src="@drawable/share" />

</LinearLayout>

自定义网格视图实现是

public class GridViewAdapterImpl extends ArrayAdapter < String > {
private final Activity context;
private final String[] data;
private int resource;

public GridViewAdapterImpl(Activity context, int resource, String[] fileNames) {
    super(context, resource, fileNames);
    this.resource = resource;
    this.context = context;
    this.data = fileNames;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    ViewHolder holder = null;

    if (row == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        row = inflater.inflate(resource, parent, false);
        holder = new ViewHolder();
        holder.imageTitle = (TextView) row.findViewById(R.id.txttitle);
        row.setTag(holder);
    } else {
        holder = (ViewHolder) row.getTag();
    }

    holder.imageTitle.setText(data[position]);
    return row;
}

static class ViewHolder {
    TextView imageTitle;
}

Gridview调用是

GridView gridView = (GridView) findViewById(R.id.gridView);

gridviewadapteripl customGridAdapter = new gridviewadapteripl(this，R.layout.row_list_videos，this . getvideofiles())；GridView . set adapter(customGridAdapter)；

gridView。setOnItemClickListener（新的onItemClick Listener（）{public void onItemClick（AdapterView父级，视图v，int位置，长id）{

只需将ImageView组件添加到您的视图容器中，并实现侦听器，请参见:

public class GridViewAdapterImpl extends ArrayAdapter < String > {
private final Activity context;
private final String[] data;
private int resource;

public GridViewAdapterImpl(Activity context, int resource, String[] fileNames) {
    super(context, resource, fileNames);
    this.resource = resource;
    this.context = context;
    this.data = fileNames;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    ViewHolder holder = null;

    if (row == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        row = inflater.inflate(resource, parent, false);
        holder = new ViewHolder();
        holder.imageTitle = (TextView) row.findViewById(R.id.txttitle);
        holder.imvShare = (ImageView) row.findViewById(R.id.share)
        // Set OnClickListener      
        holder.imageTitle.setOnClickListener(plsnTitleClickListener);
        holder.imvShare.setOnClickListener(plsnShareClickListener);
        row.setTag(holder);
    } else {
        holder = (ViewHolder) row.getTag();
    }

    holder.imageTitle.setText(data[position]);
    return row;
}

private OnClickListener plsnTitleClickListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Implement the Logic here
    }
};

private OnClickListener plsnShareClickListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Implement the Logic here
    }
};

static class ViewHolder {
    TextView imageTitle;
    ImageView imvShare;
}
