我已设法根据此Stackoverflow问题的答案创建自定义列表视图对话框。how-to-display-list-view-in-alert-dialog-in-android

这是我的对话框自定义列表视图的图像。 enter image description here

如果用户选择＆＃34;编辑帖子＆＃34;我有一个如何检索用户输入的问题？ /＆＃34;删除帖子＆＃34;对于Dialog是否有一个OnClickListener，我该如何实现呢？谢谢：）

Answer 1

mainListView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

            // Do things that use the position or 
            // the view content to understand user input

        }
    });

我认为你不必在对话框中将对话框视图定义为listview。只需创建一个简单的布局文件，如下所示：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_marginRight="100dp"
    android:layout_gravity="right">

<TextView
    android:id="@+id/edit"
    android:layout_width="wrap_content"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:paddingRight="120dp"
    android:paddingLeft="10dp"
    android:gravity="center"
    android:clickable="true"
    android:layout_height="wrap_content"
    android:textColor="@color/white"
    android:background="@drawable/selector_option_menu"
    android:text="EditPost"/>

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/white"
    />

<TextView
    android:id="@+id/delete"
    android:layout_width="wrap_content"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:paddingRight="120dp"
    android:paddingLeft="10dp"
    android:gravity="center"
    android:clickable="true"
    android:textColor="@color/white"
    android:background="@drawable/selector_option_menu"
    android:layout_height="wrap_content"
    android:text="Delete Post"/>
</LinearLayout>

创建一个自定义对话框类，扩展Dialog类，如下所示，并在onCreate() mehtod中绑定onclick监听器：

public class MyDialog extends Dialog {

Context context;
public MyDialog(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
    this.context = context;
}
public MyDialog(Context context, int theme){
    super(context, theme);
    this.context = context;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.dialog);

    findViewById(R.id.edit).setOnClickListener(...);
    findViewById(R.id.delte).setOnClickListener(...);
}
}

希望这会有所帮助。

 listview.setOnItemClickListener(new  OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                        long arg3) {

                     builder.setSingleChoiceItems(items,0,
                             new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog,int which) {
        // TODO Auto-generated method stub
            deger= which;
                                }
                  })
                   // Set the action buttons
                  .setPositiveButton("Editpost", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int id) {
                          //  Your code when user clicked on

                      }
                  })

                  .setNegativeButton("delet post", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int id) {
                         //    Your code when user clicked on

                      }
                  });

                }

            });

你总是可以使用同样的事情的上下文菜单。

首先在ListView上注册一个监听器：

registerForContextMenu(myListView);

设置上下文菜单选项：

       @Override  
    public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {  
    super.onCreateContextMenu(menu, v, menuInfo);  
    if (v==myLIstView)
    {
        menu.setHeaderTitle("Optional title");
        menu.add(0, v.getId(), 0,"Edit post"); 
        menu.add(0, v.getId(), 0,"Delete post");
    }


    }

捕获并对结果做一些事情：

    @Override
public boolean onContextItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    long num= info.id;
    if(item.getTitle()=="Edit post")
    {
        edit a post
    }
    else if(item.getTitle()=="Delete post"){
        delete a post
    }

    }
    return super.onContextItemSelected(item);
}
