Android如何对同一个按钮同时使用OnClick和长按(3秒) [英] Android how to use both OnClick and Long press(3 sec) for same Button

问题描述

在我的application中，我需要对button做普通的click时做一些Action A，同时还需要在按住同一按钮超过3秒的同时做一些其他Action B. 我已经尝试过以下代码

In my application I need to do some Action A while doing normal click for the button and also need to do some other Action B while holding the same button for more than 3 sec. I have tried this below code

private boolean isMoved = false;
    final Runnable runr = new Runnable() {

                    @Override
                    public void run() {
                        // Your code to run on long click
                        System.out.println("long pressed for 3 sec");

                    }
                };

                final Handler handel = new Handler();
                contactButton.setOnTouchListener(new View.OnTouchListener() {

                    @Override
                    public boolean onTouch(View arg0, MotionEvent arg1) {
                        switch (arg1.getAction()) {
                        case MotionEvent.ACTION_DOWN:
                            isMoved = false;
                            handel.postDelayed(runr,3000);
                            break;          
                        case MotionEvent.ACTION_MOVE:
                            isMoved = true;

                        case MotionEvent.ACTION_UP:
                            if(!isMoved)
                                System.out.println("button single click");

                        default:
                            handel.removeCallbacks(runr);
                            break;

                        }
                        return true;

                    }
                });

但是它没有按我期望的那样工作，请任何人指导我完成此操作.

But it is not working like what I expect,anyone please guide me to complete this operation.

推荐答案

Jamal. 您真的需要等待3秒钟吗?

Jamal. You really need to wait for 3 secs?

如果不需要等待3秒钟，请对单击操作使用setOnClickListener方法，对长按操作使用setOnLongClickListener方法.

If you don't need to wait for 3 secs, use the methods setOnClickListener for single click actions, and setOnLongClickListener for long click actions.

您可以在以下链接中查看它:

如果您确实需要等待3秒钟，则必须检查ACTION_UP和ACTION_DOWN时间戳之间的时差.

In the case you really need to wait for 3 secs, you have to check the difference between the timestamp of the ACTION_UP and ACTION_DOWN.

public class YourClass {    
private MotionEvent mLastEvent = MotionEvent.ACTION_UP;

final Runnable runr = new Runnable() {

                    @Override
                    public void run() {
                        if(mLastEvent == MotionEvent.ACTION_MOVE) {
                            // Your code to run on long click
                        }
                    }
                };

final Handler handel = new Handler();
contactButton.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View arg0, MotionEvent arg1) {
        mLastEvent = arg1.getAction();
        switch (arg1.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    handel.postDelayed(runr,3000);
                    break;          
                case MotionEvent.ACTION_MOVE:
                    break;
                case MotionEvent.ACTION_UP:
                default:
                    handel.removeCallbacks(runr);
                    break;

            }
                return true;
        }
    });

}
