如何在listview外设置按钮

Question

在我的活动中，我有一个listview和一个按钮。每一个都有各自的目的。

我的listview显示另一个活动中的项目详细信息。

    public class MainActivity extends AppCompatActivity implements ListView.OnItemClickListener{

   private Button buttonaddticket;

    private ListView listView;
     @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.MainActivity );

            listView = (ListView) findViewById(R.id.srListView);

            listView.setOnItemClickListener(this);

            buttonaddticket = (Button) findViewById(R.id.btnaddticket);

            //Setting listeners to button
            buttonaddticket.setOnClickListener((View.OnClickListener) this);

        }
        .
        .
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent intent = new Intent(this, SingleTicket.class);
        .
        }


    public void onClick(View v) {
        if(v == buttonaddticket){
        .
        .
        }
    }
        }

问题是如何在相同的活动中为按钮实现onClickListener？

Answer 1

您可以为活动实现多个侦听器

public class MainActivity extends AppCompatActivity implements ListView.OnItemClickListener,View.OnClickListener{

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
         // handle listview on item click
    }

    @Override
    public void onClick(View view){
         switch (view.getId()){
                    //handle multiple view click events
         }
    }

}
