Question

我有一个可点击的列表视图以及一个也可点击的按钮。问题是我不能让按钮做任何事情（它显示点击/突出显示但我的动作没有执行）。

这是我的Photo.class：

public class Photos extends MyBaseMenuOptions implements OnItemClickListener {
    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_photos);
            LayoutInflater inflater = Photos.this.getLayoutInflater();

            final View buttonView = inflater.inflate(R.layout.list_item, null);

            Button button = (Button) buttonView.findViewById(R.id.trash);

            button.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {
                    // Perform action on click   
                    Toast.makeText(getApplicationContext(), "this is my Toast message!!! =)",
                               Toast.LENGTH_LONG).show();
                }
            });

    ...

listView = (ListView) findViewById(R.id.list);
            CustomListViewAdapter adapter = new CustomListViewAdapter(this,
                    R.layout.list_item, rowItems);
            listView.setAdapter(adapter);
            listView.setOnItemClickListener(this);

我在课程中也有一个@Override public void onItemClick(AdapterView<?> parent, View view, int position,long id) {，但是当您点击列表视图时

这是我的list_item.xml

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

        android:paddingLeft="10dp"
        android:paddingRight="10dp" />

    <TextView

        android:paddingBottom="10dp"
        android:textColor="#CC0033"
        android:textSize="16dp" />

    <TextView
        android:id="@+id/desc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/title"
        android:layout_toRightOf="@+id/icon"
        android:paddingLeft="10dp"
        android:textColor="#3399FF"
        android:textSize="14dp"         />
        <Button
        android:id="@+id/trash"
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:layout_alignParentRight="true"
        android:focusable="false"
        android:descendantFocusability="blocksDescendants" 

         />

在方法getView

中的适配器中

public View getView(int position, View convertView, ViewGroup parent) {
    View view = super.getView(position, convertView, parent);
    View childview1 = view.findViewById(R.id.beam_contact_entry_contact)
    childview1.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
                // your text
            }
    });
    View childview2 = view.findViewById(R.id.beam_contact_entry_invite);
    childview2.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
                // your text 2
            }
    });

    return view;
}

Answer 2

我认为你应该在适配器的按钮上设置onClickListener。

类似的东西：

    @Override
public View getView(int position, View convertView, ViewGroup parent) {

//填充你的手机

        Button button = (Button) buttonView.findViewById(R.id.trash);

        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // Perform action on click   
                Toast.makeText(getApplicationContext(), "this is my Toast message!!! =)",
                           Toast.LENGTH_LONG).show();
            }
        });

}

Answer 3

您必须在适配器中为按钮编写click事件。在适配器的get view方法中编写click事件的按钮，只有你才能得到按钮实例。祝你好运

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
              LayoutInflator inflater = LayoutInflator.from(context);
              if(convertview == null {
                convertview = inflater .inflate(R.layout.listitem, parent, false);
               }                
               Button button = (Button) convertView.findViewById(R.id.trash);
                  button.setOnClickListener(new View.OnClickListener() {
                  public void onClick(View v) { 
            Toast.makeText(getApplicationContext(), "this is my Toast message!!! =)",
                       Toast.LENGTH_LONG).show();
        }
    });
       return convertview;

这可行祝你好运

无法获得按钮onclicklistener以使用listview
