如何添加整個佈局中的Android

Question

withing主要佈局在我試過下面的代碼主要佈局 中添加兩種佈局，但是這給了錯誤，同時設置佈局框架，並同時增加其進入視野

public class MainActivity extends Activity { 

FrameLayout rootLayout; 
FrameLayout frame1,frame2; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    rootLayout=new FrameLayout(getApplicationContext()); 
    frame1=(FrameLayout)findViewById(R.layout.frame1); 
    frame2=(FrameLayout)findViewById(R.layout.frame2); 

    LayoutParams param1=new FrameLayout.LayoutParams(180,300); 
    LayoutParams param2=new FrameLayout.LayoutParams(180,300); 

    param1.gravity=Gravity.LEFT; 
    param2.gravity=Gravity.RIGHT; 

    param1.setMargins(0, 0, 30, 30); 
    param2.setMargins(30, 0, 0, 30); 


    frame1.setLayoutParams(param1); 
    frame2.setLayoutParams(param2); 

    rootLayout.addView(frame1); 
    rootLayout.addView(frame2); 

} 
}

你必須從其父View刪除這兩個frame1和frame2查看...

，這可以幫助你......

FrameLayout rootLayout; 
    FrameLayout frame1, frame2; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     rootLayout = new FrameLayout(this); 
     frame1 = (FrameLayout) getLayoutInflater().inflate(R.layout.frame1,null); 
     frame2 = (FrameLayout) getLayoutInflater().inflate(R.layout.frame2, null); 

     FrameLayout.LayoutParams param1 = new FrameLayout.LayoutParams(180, 300); 
     FrameLayout.LayoutParams param2 = new FrameLayout.LayoutParams(180, 300); 

     param1.gravity = Gravity.LEFT; 
     param2.gravity = Gravity.RIGHT; 

     param1.setMargins(0, 0, 30, 30); 
     param2.setMargins(30, 0, 0, 30); 

     frame1.setLayoutParams(param1); 
     frame2.setLayoutParams(param2); 

     rootLayout.addView(frame1); 
     rootLayout.addView(frame2); 
     setContentView(rootLayout); 
    }
