Android RelativeLayout LayoutParams不能强制转换为FrameLayout LayoutParams

我正在尝试动态添加图像，因为imageview源是可变的，图像计数也是可变的

public class MatchingGame extends AppCompatActivity {
    String TAG = "Chic";
    RelativeLayout rLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, "matchinggame OnCreate");
        super.onCreate(savedInstanceState);
        rLayout = new RelativeLayout(this);
        setContentView(rLayout);
        Log.d(TAG, "mx");
       // rLayout = (RelativeLayout) findViewById(R.id.relative_layout);
        RelativeLayout.LayoutParams rLayParams =
                new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
        rLayParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT,RelativeLayout.CENTER_IN_PARENT);
        Log.d(TAG, "mxx");
        rLayout.setLayoutParams(rLayParams);
        Log.d(TAG, "mmx");
      ImageView img1 = new ImageView(this);
       img1.setImageResource(R.drawable.ic_launcher);
        img1.setTag(1);
        Log.d(TAG, "qx");
        rLayout.addView(img1);
        Log.d(TAG, "mqqx");
        rLayParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT,RelativeLayout.CENTER_IN_PARENT);
      //  rLayout.setLayoutParams(rLayParams);
        ImageView img2 = new ImageView(this);
        img1.setImageResource(R.drawable.b3_1);
        img1.setTag(2);
        rLayout.addView(img2);


    }

}

但我有一个错误：

java.lang.ClassCastException: android.widget.RelativeLayout$LayoutParams cannot be cast to android.widget.FrameLayout$LayoutParams

我想是关于这一行的

java.lang.ClassCastException: android.widget.RelativeLayout$LayoutParams cannot be cast to android.widget.FrameLayout$LayoutParams

我需要把左中心的图像，并在另一边，其他图像，所以我需要对齐的家长和大小规则

但它会带来错误

我有一个布局

<?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:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:id="@+id/relative_layout"
    tools:context=".games.MatchingGame">



</RelativeLayout>

我需要这个布局吗？因为我已经动态创建了布局

我也尝试过放置这个静态布局，尝试过使用

findviewbyd

制作，但总是出现相同的错误

我可以看到没有

setlayoutparams

方法的图像。但当然，没有任何规则，所以所有图像都在左上角

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, "matchinggame OnCreate");
        super.onCreate(savedInstanceState);
        rLayout = new RelativeLayout(this);
        setContentView(rLayout);
        Log.d(TAG, "mx");
       // rLayout = (RelativeLayout) findViewById(R.id.relative_layout);

        rLayout.setBackgroundColor(Color.RED);
        RelativeLayout.LayoutParams rLayParams = new RelativeLayout.LayoutParams(140,140);
        RelativeLayout.LayoutParams rLayParams1 = new RelativeLayout.LayoutParams(140,140);
        RelativeLayout.LayoutParams rLayParams2 = new RelativeLayout.LayoutParams(140,140);

        rLayParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
        rLayParams.addRule(RelativeLayout.CENTER_IN_PARENT);
       // rLayout.setLayoutParams(rLayParams);

      ImageView img1 = new ImageView(this);
       img1.setImageResource(R.drawable.ic_launcher);
        img1.setTag(1);
        rLayout.addView(img1,rLayParams);

        //todo burda for olacak ona gore rlayparams degisecek

       rLayParams1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        rLayParams1.addRule(RelativeLayout.CENTER_IN_PARENT);
       // rLayout.setLayoutParams(rLayParams);
        ImageView img2 = new ImageView(this);
        img2.setImageResource(R.drawable.b3_1);
        img2.setTag(2);
        int i=2;
        img2.setId(R.id.img11);
        rLayout.addView(img2,rLayParams1);

        rLayParams2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
        rLayParams2.addRule(RelativeLayout.BELOW,R.id.img11);
        // rLayout.setLayoutParams(rLayParams);
        ImageView img3 = new ImageView(this);
        img3.setImageResource(R.drawable.b3_1);
        img3.setTag(3);
        rLayout.addView(img3,rLayParams2);

    }

我是这样解决的。为每个图像创建不同的relativelayoutparams（因为它们有不同的规则）和

而不是这个

 // rLayout.setLayoutParams(rLayParams);

我创造了这个

rLayout.addView(img1,rLayParams);

它成功了。
