我有以下示例:
当我单击 Tab2 时,活动不适合在 android 屏幕的开头和直到 Tabs 行之间。为什么?我该怎么做才能尝试适应屏幕?
Main.java
public class Tabs_androidActivity extends ActivityGroup {
public TabHost mTabHost;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
tabHost.setup(this.getLocalActivityManager());
TabSpec spec1=tabHost.newTabSpec("Tab 1");
spec1.setContent(R.id.tab1);
spec1.setIndicator("Tab 1");
TabSpec spec2=tabHost.newTabSpec("Tab 2");
spec2.setIndicator("Tab 2");
spec2.setContent(new Intent(this, Tab2.class));
TabSpec spec3=tabHost.newTabSpec("Tab 3");
spec3.setIndicator("Tab 3");
spec3.setContent(R.id.tab3);
tabHost.addTab(spec1);
tabHost.addTab(spec2);
tabHost.addTab(spec3);
tabHost.setCurrentTab(0);
}
}
Tab2.java
public class Tab2 extends Activity {
/** Called when the activity is first created. */
TextView call;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.logs);
///....
}
}
和 main.xml
<?xml version="1.0" encoding="utf-8"?>
