能够与海誓山盟多个onTouch方法呢？ [英] Ability to have multiple onTouch methods with eachother?

问题描述

的 startButton 有一个onTouchListener，当pressed，启动媒体播放器（ MP 在我源），使相同的按钮有一个停止功能吧。

The startButton has an onTouchListener that, when pressed, starts a media player (mp in my source) and makes the same button have a stop function to it.

例如：
用户点击启动按钮和播放音乐。然后用户点击相同的按钮（现在已经停止的的setText）停止音乐播放器。

For example: The user hits the start button and the music plays. Then the user hits the same button (which now has a setText of "Stop") to stop the music player.

是否有可能有一个方法中的多个onTouchListener（S）？

Is it possible to has multiple onTouchListener(s) within a method?

startButton.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_DOWN) {

                mp.start();
                timeLeft.setText("Status: Initiated");
                startButton.setText("Stop Dreaming");

                startButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View arg0) {
                        mp.stop();

                    }

                });

这是我目前有...我将如何正确设置？

This is what I currently have... How would I set this up correctly?

推荐答案

我建议你使用一个切换按钮，用于这项工作：

I suggest you use a toggle button for this endeavor:

public void onToggleClicked(View view) {
    // Is the toggle on?
    boolean on = ((ToggleButton) view).isChecked();

    if (on) {
        mp.start();
            timeLeft.setText("Status: Initiated");
            startButton.setText("Stop Dreaming");
    } else {
        mp.stop();
    }
}
