连点处理，禁止按钮在短时间内被多次点击

在做App的过程中，当点击某个按钮的时候，如果不做连点处理，会造成按钮在短时间内被点击多次的情况。

为了避免这种情况的发生，我们需要自定义一个抽象类 CustomClickListener 并继 View.OnClickListener

abstract class CustomClickListener implements View.OnClickListener {

    private static final int MIN_CLICK_DELAY_TIME = 1000;    // 设置1秒内只能点击一次

    private long lastClickTime = 0;

    private int id = -1;

    @Override
    public void onClick(View v) {
        long currentTime = Calendar.getInstance().getTimeInMillis();
        int mId = v.getId();
        if (id != mId) {
            id = mId;
            lastClickTime = currentTime;
            onNoDoubleClick(v);
            return;
        }
        if (currentTime - lastClickTime > MIN_CLICK_DELAY_TIME) {
            lastClickTime = currentTime;
            onNoDoubleClick(v);
        }
    }

    protected abstract void onNoDoubleClick(View v);

}

将连点处理写入到需要实现的类里面

/**
 *
 * 控件中有一个按钮，一秒只能点击一次生效
 *
 */
public class MainActivity extends AppCompatActivity {

    private Button button1;

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

        button1 = (Button)findViewById(R.id.button1);

        button1.setOnClickListener(new CustomClickListener(){
            @Override
            protected void onNoDoubleClick(View v) {
                Log.d("xiazhenjie","click

");
            }
        });
    }
}
