如何创建一个设置，以便布局上有两个单选按钮
我从上一个问题中做出了更好的表示
单选按钮
- 单选按钮1
- 单选按钮2
单击RadioButton1..Activity1应显示在same screen
RadioButton1再次点击Activity2应该会显示在same screen
类似于 RadioButton2
这是我使用带有 tabhost 的选项卡执行的
由于tabhost的设计是刚性的.....是否可以像上面那样制作
如果是这样，怎么能做到......？

我不知道如何使用单选按钮，但我尝试过类似的东西
MainActivity.java
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.layout.activity_main, menu);
return true;
}
}
Fragment_1.java
public class Fragment_1 extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_fragment_1, container, false);
final EditText edtxtPersonName_Fragment = (EditText) view.findViewById(R.id.edtxtPersonName);
Button btnSayHi_Fragment = (Button) view.findViewById(R.id.btnSayHi);
btnSayHi_Fragment.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String name = edtxtPersonName_Fragment.getText().toString();
FragmentManager fm = getFragmentManager();
Fragment_2 f2 = (Fragment_2) fm.findFragmentById(R.id.fragment_content_2);
if(f2 != null && f2.isInLayout())
{
f2.setName(name);
}
Activity activity = getActivity();
if(activity != null)
{
Toast.makeText(activity, "Say&ing Hi in Progress...", Toast.LENGTH_LONG).show();
}
}
});
return view;
}
}
Fragment_2.java
public class Fragment_2 extends Fragment {
View view;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
view = inflater.inflate(R.layout.fragment_fragment_2, container, false);
return view;
}
public void setName(String name)
{
TextView txtName = (TextView) view.findViewById(R.id.txtViewResult);
txtName.setText("Hi " + name);
}
}
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="fill_parent" >

我仍然收到日志错误
