OnClickListener在导航抽屉中不起作用

Question

当我开发一个具有导航抽屉的应用程序时，它可以正常工作，但是我放置了两个图像视图，在这些视图中它们不会触发onClickListener ..请告诉我如何实现onclciklistener来像编辑和删除操作一样工作。 。 和

rowlayout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/relative">

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toRightOf="@+id/imageView1"
        android:src="@drawable/ic_menu_delete" />

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:text="Medium Text"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/ic_menu_edit" />

</RelativeLayout>

                            @Override
                            public void onClick(DialogInterface dialog,
                                    int which) {
                                userinput = input.getText().toString();

                                // int length2 = userinput.length();

                                adapter = new ArrayAdapter<String>(
                                        getApplicationContext(),

                                        listItems);
                                mDrawerList.setAdapter(adapter);

                builder2.show();
            }

Answer 1

您的代码工作正常。

但是问题是您单击了ListItem之后将onClick设置为ImageView

您必须单击到ListItem ，然后才能单击到ImageView 。

请将此代码移到onItemClick之外

ImageView edit_image = (ImageView) findViewById(R.id.imageView1);
            edit_image.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub

                    Toast.makeText(getApplicationContext(), "clicked", 3000)
                            .show();

                }
 });

Answer 2

您必须创建一个自定义阵列适配器并将其设置为抽屉列表视图。 在自定义适配器getView（）上扩展项目布局时，找到图像视图并设置侦听器（这将是内部子项）

@Override
public View getView(int position , View contentView , ViewGroup parent)
{
    View row  = ((Activity)mContext).getLayoutInflater().inflate(R.layout.rowlayout, null);

    ImageView imageView2  = (ImageView) row.findViewById(R.id. imageView2);
    imageView2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // handle the edit click here
        }
    });

   ImageView imageView1  = (ImageView) row.findViewById(R.id. imageView1);
    imageView1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // handle the delete click here
        }
    });

    return row;
}
