在我的音乐播放器为Android需要帮助 [英] Need assistance on my Music Player for android

问题描述

所以我previously问过类似的问题，只拿到了几点意见话说，谷歌搜索了，我做到了。我什么也没有发现。那么什么是为我工作。

So I previously asked a similar question and only got a few comments saying search up on google, and I did. I found nothing. Well nothing that worked for me.

我想要做的是，扩大我的音乐播放器。例如...我想创建从我的设备会显示所有的音乐文件，内置一个库。当我选择歌曲，它会播放。并在底部，它会显示以下按钮 - 洗牌，previous歌曲，播放/暂停，下一首歌曲，复读功能

What I want to do is, expand my music player. for example... I would like to create an inbuilt library that displays all the music files from my device. And when I select the song it'll play. And at the bottom it'll display the following buttons - shuffle, previous song, play/pause, next song, repeat function"

下面是我的MainActivity -

Here's my MainActivity -

package com.ascendapps.holoplayer;

import android.app.Activity;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    MediaPlayer mediaPlayer;

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

        Button play = (Button) findViewById(R.id.play);
        play.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                Uri path = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.dummy);
                mediaPlayer = MediaPlayer.create(MainActivity.this, path);
                mediaPlayer.start();
            }
        });

        Button stop = (Button) findViewById(R.id.stop);
        stop.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                if(mediaPlayer.isPlaying()) {
                    mediaPlayer.stop();
                    mediaPlayer.release();
                }
            }
        });
    }

    // --
    @Override
    protected void onDestroy() {
        if(mediaPlayer!=null && mediaPlayer.isPlaying()) {
            mediaPlayer.stop();
            mediaPlayer.release();mediaPlayer = null;
        }
        super.onDestroy();
    }
}

这是我的activity_main.xml中

And here is my activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/play"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="2.5dip"
        android:background="#ff4c4c"
        android:text="@string/Play" />

    <Button
        android:id="@+id/stop"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="2.5dip"
        android:background="#4cb4ff"
        android:text="@string/Stop" />

</LinearLayout>

这是如何做到以上将是好心AP preciated任何帮助。
