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。
含義不說了，大概意思就這樣。
下面來看他的用法：
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);
}
}
};
