按钮的双击和三击

1、布局代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    >

    <Button
        android:id="@+id/shuangji"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:text="双击"
        android:textSize="25sp"
        />

    <Button
        android:id="@+id/sanji"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:text="三击"
        android:textSize="25sp"
        />

</LinearLayout>

2、Java代码：

public class MainActivity extends Activity {

    /**
     * 双击按钮
     */
    Button shuangji;

    /**
     * 三击按钮
     */
    Button sanji;

    /**
     * 时间单位。这里默认设置1000毫秒，判断是否是在这1000毫秒之内用户双击或者三击了
     */
    private static final int TIME_UNIT = 1000;

    long[] mHit = new long[2];

    long[] mHits = new long[3];

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

        shuangji = (Button) findViewById(R.id.shuangji);
        sanji = (Button) findViewById(R.id.sanji);

        shuangji.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                System.arraycopy(mHit, 1, mHit, 0, mHit.length - 1);
                mHit[mHit.length - 1] = SystemClock.uptimeMillis();
                if (mHit[0] >= (SystemClock.uptimeMillis() - TIME_UNIT)) {
                    //点击处理事件
                    System.out.println("我被双击了....");
                }
            }
        });

        sanji.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                System.arraycopy(mHits, 1, mHits, 0, mHits.length - 1);
                mHits[mHits.length - 1] = SystemClock.uptimeMillis();
                if (mHits[0] >= (SystemClock.uptimeMillis() - TIME_UNIT)) {
                    //点击处理事件
                    System.out.println("我被三击了....");
                }
            }
        });
    }
}
