我triying用于我的项目注释部分的动态布局，但是当我的setText的TextView的动态地输出仅出现在屏幕的上方。而且它把输出过其它输出

I am triying to use dynamic layout for comment part of my project but when i settext of textview dynamicly the output only appears in top of the screen. And it puts the output over the other outputs

RelativeLayout ll=(RelativeLayout) findViewById(R.id.rl);
        for(int i = 0; i < 20; i++) {
        TextView cb = new TextView(this);
        cb.setText("YORUMLAR"+yorum[0]+i);

         cb.setTextSize(30);
          ll.addView(cb); 

        }

那么，怎样才能把我的输出屏幕线性的底部。

So how can i put the output on the bottom of the screen linearly.

推荐答案

您应该使用的LinearLayout 自动添加一个的TextView 层出不穷。

You should use LinearLayout to automatically add one TextView after another.

假设你的生活不能没有 RelativeLayout的，你需要动态生成的ID为所有的TextView 您创建为了把一个视图下另一个。下面是例子：

Assuming you can't live without RelativeLayout, you'll need to dynamically generate ids for all TextView you create in order to put one view under another. Here is example:

public class HelloWorld extends Activity
{       
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {       
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

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

        Random rnd = new Random();
        int prevTextViewId = 0;     
        for(int i = 0; i < 10; i++)
        {                       
            final TextView textView = new TextView(this);
            textView.setText("Text "+i);     
            textView.setTextColor(rnd.nextInt() | 0xff000000);            

            int curTextViewId = prevTextViewId + 1;
            textView.setId(curTextViewId);
            final RelativeLayout.LayoutParams params = 
                new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, 
                                                RelativeLayout.LayoutParams.WRAP_CONTENT);

            params.addRule(RelativeLayout.BELOW, prevTextViewId);
            textView.setLayoutParams(params);

            prevTextViewId = curTextViewId;
            layout.addView(textView, params);
        }              
    }    
}
