LinearLayout，weightSum無法正常工作

-1

我有一個基本活動和主要活動，但在主要活動中，我已應用weightsum，但其工作不正常。下面是預期和電流輸出 LinearLayout，weightSum無法正常工作

MainActivity.java

public class MainActivity extends BaseActivity { 
    LinearLayout dynamicContent,bottonNavBar; 


    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent); 
     bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar); 
     View wizard = getLayoutInflater().inflate(R.layout.activity_main, null); 
     dynamicContent.addView(wizard); 
} 
}

Mainactivity.xml

     radioGroup1=(RadioGroup)findViewById(R.id.radioGroup1);

         break;

'weightSum'是**完全可選**。此外，加權大小（只有一個！在寬度或高度之間選擇）必須是**完全0dp **。此外，嵌套佈局會影響性能。 ** **負。有人沒有做功課，是吧？ ;） –

將每個子視圖的高度更改爲0dp – codeMagic

您可以在'BaseActivity'中發佈膨脹的佈局嗎？我認爲問題在那裏，因爲你的其他xml看起來是正確的。 – codeMagic

嘗試在你的Mainactivity以下 .xml

將您的孩子LinearLayout layout_height從match_parent更改爲0dp。

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:orientation="vertical" 
android:weightSum="2" 
android:layout_height="match_parent" 
android:background="#F5F5F5" 
tools:context="com.creativeframe.arun.pro.MainActivity"> 
<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:background="@drawable/cbseschool" 
    android:orientation="vertical"> 

</LinearLayout> 
<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:background="@drawable/college" 
    android:orientation="vertical"> 

    </LinearLayout> 

    </LinearLayout>

在MainActivity中設置您的佈局視圖如下。

public class MainActivity extends BaseActivity { 
LinearLayout dynamicContent,bottonNavBar; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    dynamicContent = (LinearLayout) findViewById(R.id.dynamicContent); 
    bottonNavBar= (LinearLayout) findViewById(R.id.bottonNavBar); 

} 
}

這將是更好的解釋*你已經改變了什麼，以及*如何*它將解決問題，以便其他人可以更好地學習。 – codeMagic

不，它不工作 –

請嘗試編輯的答案。 –

對於水平分使用

android:layout_width="0dp"

和對於垂直用途：

android:layout_height="0dp"

實施例：

 <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical"> 
     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="0dp" 
      android:layout_weight="1"> 
      <ImageView 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:scaleType="fitXY" 
       android:src="@mipmap/ic_launcher"/> 
     </LinearLayout> 
     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="0dp" 
      android:layout_weight="1"> 
      <ImageView 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:scaleType="fitXY" 
       android:src="@mipmap/ic_launcher"/> 
     </LinearLayout> 
    </LinearLayout>
