public class MainActivity extends AppCompatActivity{
    private final static int COUNTS = 5;//点击次数
    private final static long VALIDTIME = 1300;//有效时间
    private long[] mHits = new long[COUNTS];

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViewById(R.id.bt_my).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //mHits数组元素左移一个位置
                System.arraycopy(mHits, 1, mHits, 0, mHits.length - 1);
                //获得当前系统已经启动的时间
                mHits[mHits.length - 1] = SystemClock.uptimeMillis();
                if (mHits[0] >= (SystemClock.uptimeMillis() - VALIDTIME)) {
                    Toast.makeText(MainActivity.this, "在" + VALIDTIME + "ms内," + "点击了" + COUNTS + "次", Toast.LENGTH_SHORT).show();
                }
            }
        });

    }
