我试图通过点击它从listview移动到其他布局帮助我plz

public class ListViewActivity extends Activity {
    private ListView lv1;

    private String lv_arr[] = {"Android", "iPhone", "BlackBerry", "Nokia"};

    @Override
    public void onCreate(Bundle x)
    {
        super.onCreate(x);
        setContentView(R.layout.activity_main);

        lv1=(ListView)findViewById(R.id.ListView01);
        lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , lv_arr));
        //lv1.setTextFilterEnabled(true);
        lv1.setOnItemClickListener(new OnItemClickListener() {

        }
    }
}

Answer 1

使用onItemClickListener。
这很简单。如果你搜索周围你会得到这个。

 List.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
    Intent intent = new Intent(getApplicationContext(),SecondClass.class);
            intent.putExtra("passsomething","value_of_variable");
    startActivity(intent);

        }
    });

Answer 2

尝试以下

lv1.setOnItemClickListener(new OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
    { 
        Intent i = new Intent(ActivityName.this,SecondActivity.class);
        //  if you just want to navigate to second activity remove the below lines
        //String value = (String) arg0.getItemAtPosition(position);
        //i.putExtra("key",value);
        startActivity(i); 
});

在SecondActivity中

如果要在第二个活动中显示listview中单击的项目，请使用textview，否则忽略下面的

Bundle extras = getIntent().getExtras();
if(extras!=null)
{
     String value = extras.getString("key");
     // textview.setText(value);
}
