我正在使用片段为我的Android应用程序，我使用actionbarsherlock。当我尝试在模拟器中运行我的应用程序时，按钮不会出现只显示片段选项卡。
main xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

主要活动代码：
public class MainActivity extends SherlockFragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionbar = getSupportActionBar();
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionbar.setTitle("Dancing Fountain");
ActionBar.Tab Frag1Tab = actionbar.newTab().setText("Song List");
ActionBar.Tab Frag2Tab = actionbar.newTab().setText("About");
Fragment Fragment1 = new Fragment_1();
Fragment Fragment2 = new Fragment_2();
Frag1Tab.setTabListener(new MyTabsListener(Fragment1));
Frag2Tab.setTabListener(new MyTabsListener(Fragment2));
actionbar.addTab(Frag1Tab);
actionbar.addTab(Frag2Tab);
}
class MyTabsListener implements ActionBar.TabListener {
public Fragment fragment;
public MyTabsListener(Fragment fragment){
this.fragment = fragment;
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
ft.replace(R.id.fragment_container, fragment);
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
}
Fragment_1代码：
public class Fragment_1 extends SherlockFragment {
private EditText textField1;
private EditText textField2;
private EditText textField3;
private EditText textField4;
private EditText textField5;
private Button button1;
private Button button2;
private Button button3;
private Button button4;
private Button button5;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.fragment_1, container, false);
button1 = (Button)v.findViewById(R.id.btn1);
button2 = (Button)v.findViewById(R.id.btn2);
button3 = (Button)v.findViewById(R.id.btn3);
button4 = (Button)v.findViewById(R.id.btn4);
button5 = (Button)v.findViewById(R.id.btn5);
textField1 = (EditText)v.findViewById(R.id.editText1);
textField2 = (EditText)v.findViewById(R.id.editText2);
textField3 = (EditText)v.findViewById(R.id.editText3);
textField4 = (EditText)v.findViewById(R.id.editText4);
textField5 = (EditText)v.findViewById(R.id.editText5);
textField1.setVisibility(View.GONE);
textField2.setVisibility(View.GONE);
textField3.setVisibility(View.GONE);
textField4.setVisibility(View.GONE);
textField5.setVisibility(View.GONE);
return v;
}
public void buttonClicked1(View v){
Log.d("MyTag", "The song has been successfully added!");
new asynctask().execute(textField1);
}
public void buttonClicked2(View v) {
Log.d("MyTag", "The song has been successfully added!");
new asynctask().execute(textField2);
}
public void buttonClicked3(View v) {
Log.d("MyTag", "The song has been successfully added!");
new asynctask().execute(textField3);
}
public void buttonClicked4(View v) {
Log.d("MyTag", "The song has been successfully added!");
new asynctask().execute(textField4);
}
public void buttonClicked5(View v) {
Log.d("MyTag", "The song has been successfully added!");
new asynctask().execute(textField5);
}
}
这是我的Logcat：
