Answer 1

在设置适配器

后写下此内容

    @Override
     public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.fecilities);
            setListAdapter(new ImageAdapter(this, R.layout.fecilities, R.id.text1, R.id.image1, listItems, listImages ));
    getListView().setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
            //code specific to first list item    
            Intent myIntent = new Intent(this, NextActivity.class);
            startActivity(myIntent);      
        }
    });
}

和您的Manifest.xml

<activity  android:name=".NextActivity" />

Answer 2

试试这个..

setListAdapter(new ImageAdapter(this, R.layout.fecilities, R.id.text1, R.id.image1, listItems, listImages ));
getListView().setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {  
           Intent intent = new Intent(Facilities.this, NextActivity.class);
           startActivity(intent);
      }
});

确保NextActivity应在清单中声明。

如果我点击列表，它将转到另一个活动

要启动ListView项目上的其他活动，您需要为当前ListView添加setOnItemClickListener，然后使用onItemClick打开下一个活动：

this.getListView().setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view,
            final int pos, long id) {
        //Open next Activity here
    }
});

Answer 4

试试这个： - 将onclick监听器设置为列表视图。在里面开始其他活动，如下面

 Intent intent = new Intent(this, otherAct.class);
 startActivity(intent, 0);

另外，请不要忘记将其他活动放入清单文件中。

Answer 5

getListView.setOnItemClickListener(new OnItemClickListener() {
 public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
{
      Intent i=new Intent(Current_Activity.this,Next_Activity.class);
      startActivity(i);'                    
 }
});

Answer 6

你可以试试这个：

getListView().setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
        if (pos == 0) {
            Intent intent = new Intent(getApplicationContext(), FirstAct.class);
            startActivity(intent);
        }
        if (pos == 1) {
            Intent intent = new Intent(getApplicationContext(), SecondAct.class);
            startActivity(intent);
        }
    }
});

Answer 7

您需要实施onClickListener：

public class Facilities extends ListActivity implements OnItemClickListener

然后实现相应的方法，它看起来像这样：

@Override
public void onItemClick( AdapterView<?> parent, View view, int position, long id )
{
    // Start that new activity with some extra info from the clicked view

    // In this case the getItem() method returns an object, but your ImageAdapter
    // class may return any type you specified, of course
    Object o = this.getListAdapter().getItem( position );

    Intent intent = new Intent(Facilities.this, SomeOtherActivity.class);
    intent.putExtra( "key", o.toString() );
    startActivity(intent);
}

当然需要倾听一些内容，所以在你的onCreate()中，你最后会提到以下内容：

getListView().setOnItemClickListener(this);

现在您的其他活动应该正常启动，如果您在那里拨打getIntent()，则可以获得您从ListActivity添加的额外信息。

点击列表它将打开另一个活动
