Android 连击实现

  // 数组长度表示要点击的次数
  long[] mHits = new long[3];
  
  public void onClick(View view) {
    		System.arraycopy(mHits, 1, mHits, 0, mHits.length - 1);
    		mHits[mHits.length - 1] = SystemClock.uptimeMillis();
    		if (mHits[0] >= (SystemClock.uptimeMillis() - 500)) {
    			Toast.makeText(this, "!!!", Toast.LENGTH_SHORT).show();
    		}
    	}
