这是我的标签代码。请告诉我如何通过switch语句或简单的onclick监听器将监听器放在tab1上。此吐司消息也无法正常工作
public class TabsActivity extends Activity implements OnClickListener {
TabHost th;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tabs);
th = (TabHost)findViewById(R.id.tabhost);
th.setup();
TabSpec specs = th.newTabSpec("tag1");
specs.setContent(R.id.tab1);
specs.setIndicator("Home");
th.addTab(specs);
specs = th.newTabSpec("tag2");
specs.setContent(R.id.tab2);
specs.setIndicator("Goup");
th.addTab(specs);
specs = th.newTabSpec("tag3");
specs.setContent(R.id.tab3);
specs.setIndicator("Delete");
th.addTab(specs);
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(arg0.getId()){
case R.id.tab1:
Toast.makeText(TabsActivity.this, "Action Item 0 selected!", Toast.LENGTH_LONG).show();
break;
case R.id.tab2:
TextView text= new TextView(TabsActivity.this);
text.setText("u have created a new tab");
break;
case R.id.tab3:
break;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_tabs, menu);
return true;
}
}

如果您想要监听器操作,请单击选项卡,您应该使用:
th.setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
Toast.makeText(getApplicationContext(), "Click on tab: "+ tabId, Toast.LENGTH_SHORT).show();
}
});
