            default:

    }
}

的strings.xml

<resources>
    <string name="app_name">TG Mobile</string>
    <string name="in_app_name">TeamGym Mobile</string>
    <string name="sRnum">1</string>
    <string name="sPnum">0</string>
    <string name="sSnum">0</string>
    <string name="sTnum">0.0</string>
    <string name="sResultnum">0.00</string>
</resources>

像这样创建T3_TrampetActivity并从活动中调用你的片段：

=IF((L4-K4)*24>7.5,(L4-K4)*24-1,S(L4-K4)*24)

创建activity_main.xml，如下所示：

public class T3_TrampetActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Fragment fragment = new  T3_TrampetFragment();
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

    }
}

更新T3_TrampetFragment.java

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"                
             android:id="@+id/fragment_frame"            
             android:layout_width="match_parent"
             android:layout_height="match_parent" />

t3_trampetlayout.xml对Fragment使用相同的布局。

EditText在ImageButton上没有更改？
