有時(shí)候需要?jiǎng)討B(tài)添加數(shù)據(jù)，屏幕顯示滿了，數(shù)據(jù)需要滾動(dòng)展示。這里主要弄懂scrollTo(0, off)方法的含義喊用法。

含義不說(shuō)了，大概意思就這樣。

下面來(lái)看他的用法：

復(fù)制代碼代碼如下:

private void searchResultShow() {

TextView textView = new TextView(AFSearchActivity.this);
        textView.setText("Text View ");
        LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT
        );
        textView.setPadding(30, 15, 0, 15);
        textView.setTextSize(30);
        textView.setTextColor(Color.WHITE);
        //增加一個(gè)TextView到線性布局中
       layout.addView(textView, p);

        ImageView imageView = new ImageView(AFSearchActivity.this);
        imageView.setImageResource(R.drawable.im_dottend_line);

      //增加一個(gè)ImageView到線性布局中
        layout.addView(imageView, p);
        if(sName == null || sName.equals("")){
   textView.setText("-");
  }else{
   textView.setText(sName);
   sName = "";
    mHandler.post(mScrollToBottom);
  }
}
private Runnable mScrollToBottom = new Runnable()
    {
        @Override
        public void run()
        {
            int off = layout.getMeasuredHeight() - nameScroll.getHeight();
            if (off > 0)
            {
            nameScroll.scrollTo(0, off);
            }
        }
    };
