利用ScrollView實現佈局自動滾動
阿新 • • 發佈:2019-01-06
首先1,獲得ScrollView sc = (ScrollView) findViewById(R.id.scroll);//scroll物件
LinearLayout mlayout = (LinearLayout) findViewById(R.id.mlayout);//scrollView中包含的佈局物件
2,定義一個Handler
private final Handler mHandler = new Handler();
3,實現一個執行緒
4,開始滾動
mHandler.post(ScrollRunnable);
5,暫停滾動
mHandler.removeCallbacks(ScrollRunnable);
ScrollView強制滑到底部
scroll.fullScroll(View.FOCUS_DOWN)
LinearLayout mlayout = (LinearLayout) findViewById(R.id.mlayout);//scrollView中包含的佈局物件
2,定義一個Handler
private final Handler mHandler = new Handler();
3,實現一個執行緒
private Runnable ScrollRunnable= new Runnable() { @Override public void run() { int off = mlayout.getMeasuredHeight() - sc.getHeight();//判斷高度 if (off > 0) { sc.scrollBy(0, 30); if (sc.getScrollY() == off) { Thread.currentThread().interrupt(); } else { mHandler.postDelayed(this, 1000); } } } };
4,開始滾動
mHandler.post(ScrollRunnable);
5,暫停滾動
mHandler.removeCallbacks(ScrollRunnable);
ScrollView強制滑到底部
scroll.fullScroll(View.FOCUS_DOWN)
