膨胀失败

标签： java android xml layout-inflater

我运行了一个关于片段的基本代码。 我可以完美地运行代码，但是当我在MainActivity.java中插入一个简单的if-else时。它无法膨胀。任何的想法？ 这是Activity_main.xml 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<fragment
    android:name = "com.example.frags.LF"
    android:id="@+id/viewer"
    android:layout_height="0dp"
    android:layout_width="match_parent"/>
<fragment
android:name="com.example.frags.MF"
android:id="@+id/land2"
android:layout_width="0dp"
android:layout_height="match_parent" />
</RelativeLayout>

这是MainActivity.java 

package com.example.frags;

import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
public class MainActivity extends Activity {
private static final String TAG = "MainAct";
@Override
protected void onCreate(Bundle savedInstanceState) {
    Log.i(TAG,"Entered on Create()");
    super.onCreate(savedInstanceState);
    Log.i(TAG,"Entered on CreatedUPRT()");
    setContentView(R.layout.activity_main);
    Configuration config = getResources().getConfiguration();
    if (config.orientation == Configuration.ORIENTATION_PORTRAIT){
        Log.i(TAG,"Entered portrait mode");
        LF mt = (LF) getFragmentManager()
                .findFragmentById(R.id.viewer);
    }
    else
    {
        MF mt = (MF)getFragmentManager().findFragmentById(R.id.land2);
    }       
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
    }

}

LF.java     package com.example.frags; 

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.util.Log;

public class LF extends Fragment {
private static final String TAG = "Fragment";
@Override
public View onCreateView(LayoutInflater l, ViewGroup V, Bundle savedInstanceState)
{
    Log.i(TAG,"Entered onCreateView");
    return l.inflate(R.layout.lf, V, false);
    }

}

MF.java是

package com.example.frags;

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class MF extends Fragment {

    @Override
    public View onCreateView(LayoutInflater m, ViewGroup V, Bundle savedInstanceState){
        return m.inflate(R.id.land2, V, false);

    }
}

和mf.xml 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >



    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/land" />

</LinearLayout>

lf.xml是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/text" />

</LinearLayout>
