在代碼中設置RelativeLayout布局中標簽的android:layout_toLeftOf、android:layout_toRightOf等屬性

 

需要動態改變RelativeLayout里面控件的相對位置，經一個技術群的群友提示，找到了如下的方法，做下記錄：

 

1.  
   RelativeLayout.Layoutparams params = (RelativeLayout.LayoutParams)控件 1.getLayoutParams();
2.  
   params.addRule(RelativeLayout.LEFT_OF, R.id.控件 2);

//轉載一個布局文件，要向這個布局匯總動態添加一個button
RelativeLayout relativeLayout（RelativeLayout）getLayoutInflater().inflate(R.layout.main,null); //裝載要動態添加的按鈕布局 Button button = (Button)getLayoutInflater().inflate(R.layout.button,null); //創建一個LayoutParams對象 RelativeLayoutLayoutParamslayoutParams= new RelativeLayout。LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); layoutParams.addRule(RelativeLayout.RIGHT_OF,R.id.button1); layoutParams.addRule(RelativeLayout.BELOW,R.id.button); button.setLayoutParams(layoutParams); relativeLayout.addView(button);
