帶有動態片段的Android項目在仿真器上崩潰？

我是新來的android和環顧網絡上的各種教程來學習的概念。帶有動態片段的Android項目在仿真器上崩潰？

最近我遇到了碎片，並試圖執行它。

現在我試圖實現如何動態地將一個片段添加到activity。但是當我嘗試在模擬器上啓動我的應用程序時（模擬器不崩潰），我收到崩潰報告。

這是我的代碼。

主要Activity.java

public class MainActivity extends Activity { 

    Fragment fragment; 
    Button btn1, btn2, btn3; 
    @SuppressLint("NewApi") 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     fragment = new Fragment1(); 
     btn1 = (Button) findViewById(R.id.btn1); 

     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     transaction.add(R.id.fragment_2, fragment); 
     transaction.commit(); 

     btn1.setOnClickListener(btnClickListener); 
    } 

    @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; 
    } 

    OnClickListener btnClickListener = new OnClickListener(){ 
     Fragment fragment; 
     @SuppressLint("Recycle") 
     @Override 
     public void onClick(View v) { 
      FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
      if(v == btn1){ 
       fragment = new Fragment1(); 
      } 
      transaction.replace(R.id.fragment_1,fragment); 
      transaction.addToBackStack(null); 
      transaction.commit();   
     } 

    }; 
}

activity_main.xml中

<LinearLayout 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" 
    tools:context=".MainActivity" >

    <Button 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="Fragment 1"

</LinearLayout> 

<LinearLayout 
    android:id="@+id/container" 
    android:layout_width="0dp" 
    android:layout_height="fill_parent" 
    android:layout_weight="2" 
    android:background="#000088" 
    android:orientation="vertical" /> 

</LinearLayout>

Framgent1.java

@SuppressLint("NewApi") 
public class Fragment1 extends Fragment{ 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     return inflater.inflate(R.id.fragment_1, container, false); 
    } 

}

fragment1.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" 
    android:id="@+id/fragment_1" 
    android:background="#FFDDAA"> 


</LinearLayout>

清單

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.apoos.dynamicfragment" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="11" 
     android:targetSdkVersion="18" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <activity 
      android:name="com.apoos.dynamicfragment.MainActivity" 
      android:label="@string/app_name" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 

</manifest>

我有類似fragment_1與名fragment_2片段。

Fragment_1：默認Fragment_2：點擊按鈕時出現。

唯一不同的B/W Fragment_1和Fragment_2是，他們有

不同的背景。

關於開展仿真模擬器來了，但它說，

MyApplication的不幸已經停止。

我也試過使用支持庫，但它有同樣的問題。

任何人都可以告訴我出了什麼問題嗎？或者任何一個可以指向我的教程基本的Android片段。

你在哪裏試圖從'MainActivity'加載你的'fragment 1'？ – GrIsHu

在mainActivity的onCreate方法中。 –

你的Logcat在哪裏？你必須在這一行中得到錯誤transaction.add（R.id.fragment_2，fragment）;'因爲它不能在你的佈局中得到'R.id.fragment_2'的視圖。 – GrIsHu

你應該膨脹佈局。

考慮以下爲fragment_1。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" 
    android:id="@+id/fragment_1" 
    android:background="#FFDDAA"> 


</LinearLayout>

變化片段1

return inflater.inflate(R.id.fragment_1, container, false);

到

return inflater.inflate(R.layout.fragment_1, container, false);

在你MainActivity

變化

transaction.add(R.id.fragment_2, fragment);

到

transaction.add(R.id.container, fragment);

bcoz要添加片段，其是在你的情況下，LinearLayout

<LinearLayout 
    android:id="@+id/container" // id is container not fragment_1 
    android:layout_width="0dp" 
    android:layout_height="fill_parent" 
    android:layout_weight="2" 
    android:background="#000088" 
    android:orientation="vertical" /> 

</LinearLayout>

同樣在點擊按鈕的容器，如果你有Fragment2.java

fragment = new Fragment2(); // Framgent2 
    transaction.replace(R.id.container,fragment); 
    // replace Fragment1 by Fragment 2 in the container 
    transaction.addToBackStack(null);

所有你必須使用FragmentActivity當你與Fragment

然後工作首先如果強行關閉後再次在logcat的錯誤代碼

嗨Naresh我試過，當我用支持庫來使用fragmentManager和事務 –

然後發佈logcat代碼 –

我認爲你錯過了你的xml文件一次檢查。交換活動xml文件和片段xml一次，並檢查 –

在您的MainActivity更改如下：

而不是id transaction.add(R.id.fragment_2, fragment);更改爲transaction.add(R.id.container, fragment);

相同的按鈕也點擊。

public class MainActivity extends Activity { 

    Fragment fragment; 
    Button btn1, btn2, btn3; 
    @SuppressLint("NewApi") 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     fragment = new Fragment1(); 
     btn1 = (Button) findViewById(R.id.btn1); 

     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     transaction.add(R.id.container, fragment); 
     transaction.commit(); 

    }
