android 實現ScrollView自動滾動

有時候需要動態添加數據，屏幕顯示滿了，數據需要滾動展示。這裡主要弄懂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);   
            }                          
        }   
    };
