有时候需要动态添加数据，屏幕显示满了，数据需要滚动展示。这里主要弄懂scrollTo(0, off)方法的含义喊用法。

含义不说了，大概意思就这样。

下面来看他的用法：

复制代码 代码如下:

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);

//增加一个TextView到线性布局中

layout.addView(textView, p);

ImageView imageView = new ImageView(AFSearchActivity.this);

imageView.setImageResource(R.drawable.im_dottend_line);

//增加一个ImageView到线性布局中

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);

}

}

};
