我需要执行onClick来调用另一个类的onItemSelected侦听器方法.我不知道如何在Image按钮的onClick侦听器中调用该方法,因此它将移至HomeFirstFragment类.

ItmeSelectedListener

public interface ItemSelectedListener {    public voID onItemSelected(final int position, final String content);}

LayoutActivity.java：

public class LayoutActivity extends Activity implements OnClickListener {Imagebutton btn_click;  @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_grID3);        btn_click = (Imagebutton) findVIEwByID(R.ID.btn_click);   }    @OverrIDe    public voID onClick(VIEw v) {        switch (v.getID()) {            case R.ID.btn_click:             break;        }    }}

MainActivity.java：

public class MainActivity extends ActionBaractivity implements OnTabchangelistener,ItemSelectedListener { private TextVIEw action_bar_hometext; @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);} @OverrIDe    public voID onItemSelected(int position, String content)    {        if(position==0)        {            action_bar_hometext.setText(content);            FragmentManager manager = getSupportFragmentManager();            FragmentTransaction ft = manager.beginTransaction();            HomeFirstFragment newFragment = new HomeFirstFragment();            ft.replace(R.ID.realtabcontent, newFragment);            ft.addToBackStack(null);            ft.commit();        }     }

如果我单击LayoutActivity类中的btn_click,则需要执行onClick以从MainActivity调用接口方法.

任何人都可以帮助我.谢谢.

解决方法:

您可以创建自己的侦听器,并在您自己的侦听器中单击要添加的代码块.

创建你的界面像

Interface MyListener{    public voID myClickListener(String content);}

现在在您的MainActivity中实现

public class MainActivity extends ActionBaractivity implements OnTabchangelistener,ItemSelectedListener,MyListener {    public voID myClickListener(String content){        action_bar_hometext.setText(content);        FragmentManager manager = getSupportFragmentManager();        FragmentTransaction ft = manager.beginTransaction();        HomeFirstFragment newFragment = new HomeFirstFragment();        ft.replace(R.ID.realtabcontent, newFragment);        ft.addToBackStack(null);        ft.commit();    }}
