相對佈局權重

Question

我需要在RelativeLayout的情況下找到線性佈局權重參數的替代品。

下面是LinearLayout

LinearLayout.LayoutParams fp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,0); 
fp.weight = 2; 
FrameLayout parent_frame = (FrameLayout) findViewById(R.id.frame_container); 
parent_frame.setLayoutParams(fp); 

LinearLayout.LayoutParams tp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,0); 
tp.weight = 1; 
FrameLayout popup_layout = (FrameLayout) findViewById(R.id.popup_layout_id); 
popup_layout.setLayoutParams(tp); 

我需要做相同的，如果父佈局更改爲RelativeLayout代碼， 我有下面的代碼，但輸出是黑屏。

RelativeLayout.LayoutParams fp = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,0); 
    //fp.weight = 2; 

    FrameLayout parent_frame = (FrameLayout) findViewById(R.id.frame_container); 
    parent_frame.setLayoutParams(fp); 

    RelativeLayout.LayoutParams tp = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,0); 
    //tp.weight = 1; 

    FrameLayout popup_layout = (FrameLayout) findViewById(R.id.popup_layout_id); 
    popup_layout.setLayoutParams(tp); 

基本上我需要的是顯示2佈局垂直70％的第一佈局和與第二個30％屏幕，並且因爲它需要大量的代碼我不能在XML使用LinearLayout變化。

新PercentRelativeLayout是你的朋友：
