と、このエラー、あなたはそれを修正する方法を、私を助けることができますか？あなたのコードで

Answer 1

あなたがそうimport android.view.ViewGroup.LayoutParams

Answer 2

をimport android.widget.RelativeLayout.LayoutParams;

を削除し、追加android.view.ViewGroup.LayoutParams

の代わりにimport android.widget.RelativeLayout.LayoutParams;をインポートしているだけでCntが+ Oため、不要な輸入

Answer 3

あなたが作る必要があるの削除]をクリックします親レイアウトのLayoutParamsオブジェクト下のレイアウトの例では、LinearLayoutの高さと幅を設定するために、RelativeLayoutのLayoutParmasをLinearLayout自体ではなくする必要があります。以下

<?xml version="1.0" encoding="utf-8"?> 
    <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" 
    tools:context=".newsblog.NewsDetailsActivity" 
    > 

     <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"/> 


</RelativeLayout> 


//IN ACTIVITY 
RelativeLayout.LayoutParams params=new RelativeLayout.LayoutParams(30,30); //Parent Params 
linearLayout.setLayoutParmas(params); //Child Layout 


//If you want to set the params of the Relative Layout above. It seems it doesn't have any parent but it has a parent created by android framework which is a frame layout. So 
FrameLayout.LayoutParmas params=new FrameLayout.LayoutParmas(30, 30);//FrameLayout is a parentcreated by anroid frame work 
relativeLayout.setLayoutParmas(params); ////Here Relative layout is child 

Answer 4

使用コード：

imageView.setLayoutParams（新しいandroid.widget.RelativeLayout.LayoutParams（ViewPager.LayoutParams.MATCH_PARENT、ViewPager.LayoutParams.MATCH_PARENT））。
