安卓实现多次点击

long[] mHits = new long[2];

			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				System.arraycopy(mHits, 1, mHits, 0, mHits.length - 1);
				mHits[mHits.length - 1] = SystemClock.uptimeMillis();
				if (mHits[0] >= (SystemClock.uptimeMillis() - 500)) {

				}
			}
