Question

我想在Sliding Drawer的内容中添加一些按钮，其内容是相对布局。该按钮将在Java代码中定义，相对布局已在xml布局中定义。所以，假设我想添加4个按钮：

for (int i=0; i<4; i++) {
     Button btn = new Button(this);
     btn.setId(i);
     btn.setText("some_text");
}

然后我初始化相对布局：

RelativeLayout layout = (RelativeLayout)findViewById(R.id.slidingDrawerContent);

现在如何将所有Button添加到相对布局中？谢谢你的帮助。

Answer 1

RelativeLayout layout = (RelativeLayout)findViewById(R.id.slidingDrawerContent);
for (int i=0; i<4; i++) {
     Button btn = new Button(this);
     btn.setId(i);
     btn.setText("some_text");
    layout.add(btn); 
}

或

有点提前

 RelativeLayout layout = (RelativeLayout)findViewById(R.id.slidingDrawerContent);
 RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT );


    for (int i=0; i<4; i++) {
         Button btn = new Button(this);
         btn.setId(i);
         btn.setText("some_text");

        // lp.addRule(RelativeLayout.RIGHT_OF, <Id>);

         layout.addView(tv2, lp); 
    }

Answer 2

只需这样做：

layout.addView(btn);
