Android仿QQ音乐播放界面代码

以下是一个简单的Android仿QQ音乐播放界面的代码示例：

1. 首先，在布局文件中添加以下代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageViewAlbumArt"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_centerInParent="true"
        android:src="@drawable/album_art_placeholder" />

    <TextView
        android:id="@+id/textViewSongTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/imageViewAlbumArt"
        android:layout_centerHorizontal="true"
        android:text="Song Title"
        android:textColor="@android:color/black"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/textViewArtistAlbum"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/textViewSongTitle"
        android:layout_centerHorizontal="true"
        android:text="Artist - Album"
        android:textColor="@android:color/darker_gray"
        android:textSize="16sp" />

    <SeekBar
        android:id="@+id/seekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/textViewArtistAlbum"
        android:layout_marginTop="20dp"
        android:max="100"
        android:paddingLeft="20dp"
        android:paddingRight="20dp"
        android:progress="0"
        android:thumb="@drawable/seekbar_thumb" />

    <TextView
        android:id="@+id/textViewCurrentTime"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/seekBar"
        android:layout_marginTop="10dp"
        android:layout_marginLeft="20dp"
        android:text="00:00"
        android:textColor="@android:color/darker_gray"
        android:textSize="14sp" />

    <TextView
        android:id="@+id/textViewDuration"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/seekBar"
        android:layout_alignParentRight="true"
        android:layout_marginTop="10dp"
        android:layout_marginRight="20dp"
        android:text="00:00"
        android:textColor="@android:color/darker_gray"
        android:textSize="14sp" />

    <LinearLayout
        android:id="@+id/linearLayoutPlayerControls"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/textViewCurrentTime"
        android:layout_marginTop="10dp"
        android:gravity="center">

        <ImageButton
            android:id="@+id/imageButtonPrevious"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:padding="10dp"
            android:src="@drawable/ic_skip_previous_black_24dp" />

        <ImageButton
            android:id="@+id/imageButtonPlayPause"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:padding="10dp"
            android:src="@drawable/ic_play_arrow_black_24dp" />

        <ImageButton
            android:id="@+id/imageButtonNext"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:padding="10dp"
            android:src="@drawable/ic_skip_next_black_24dp" />

    </LinearLayout>

</RelativeLayout>

2. 在Java类中，添加以下代码：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private ImageView imageViewAlbumArt;
    private TextView textViewSongTitle, textViewArtistAlbum, textViewCurrentTime, textViewDuration;
    private SeekBar seekBar;
    private ImageButton imageButtonPrevious, imageButtonPlayPause, imageButtonNext;

    private MediaPlayer mediaPlayer;
    private Handler handler;
    private Runnable runnable;

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

        imageViewAlbumArt = findViewById(R.id.imageViewAlbumArt);
        textViewSongTitle = findViewById(R.id.textViewSongTitle);
        textViewArtistAlbum = findViewById(R.id.textViewArtistAlbum);
        textViewCurrentTime = findViewById(R.id.textViewCurrentTime);
        textViewDuration = findViewById(R.id.textViewDuration);
        seekBar = findViewById(R.id.seekBar);
        imageButtonPrevious = findViewById(R.id.imageButtonPrevious);
        imageButtonPlayPause = findViewById(R.id.imageButtonPlayPause);
        imageButtonNext = findViewById(R.id.imageButtonNext);

        // 设置监听器
        imageButtonPrevious.setOnClickListener(this);
        imageButtonPlayPause.setOnClickListener(this);
        imageButtonNext.setOnClickListener(this);
        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                if (fromUser) {
                    mediaPlayer.seekTo(progress * 1000);
                    updateSeekBar();
                }
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });

        // 初始化MediaPlayer和Handler
        mediaPlayer = MediaPlayer.create(this, R.raw.song);
        handler = new Handler();

        // 设置初始状态
        updateSeekBar();
        updatePlayPauseButton();
        updateSongInfo();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.imageButtonPrevious:
                mediaPlayer.seekTo(0);
                updateSeekBar();
                break;
            case R.id.imageButtonPlayPause:
                if (mediaPlayer.isPlaying()) {
                    mediaPlayer.pause();
                } else {
                    mediaPlayer.start();
                }
                updatePlayPauseButton();
                break;
            case R.id.imageButtonNext:
                mediaPlayer.seekTo(mediaPlayer.getDuration());
                updateSeekBar();
                break;
        }
    }

    private void updateSeekBar() {
        seekBar.setProgress(mediaPlayer.getCurrentPosition() / 1000);
        textViewCurrentTime.setText(getFormattedTime(mediaPlayer.getCurrentPosition()));
        textViewDuration.setText(getFormattedTime(mediaPlayer.getDuration()));
        runnable = new Runnable() {
            @Override
            public void run() {
                updateSeekBar();
            }
        };
        handler.postDelayed(runnable, 1000);
    }

    private void updatePlayPauseButton() {
        if (mediaPlayer.isPlaying()) {
            imageButtonPlayPause.setImageResource(R.drawable.ic_pause_black_24dp);
        } else {
            imageButtonPlayPause.setImageResource(R.drawable.ic_play_arrow_black_24dp);
        }
    }

    private void updateSongInfo() {
        textViewSongTitle.setText("Song Title");
        textViewArtistAlbum.setText("Artist - Album");
        imageViewAlbumArt.setImageResource(R.drawable.album_art_placeholder);
    }

    private String getFormattedTime(int milliseconds) {
        int seconds = (milliseconds / 1000) % 60;
        int minutes = (milliseconds / (1000 * 60)) % 60;
        return String.format("%02d:%02d", minutes, seconds);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mediaPlayer.release();
        handler.removeCallbacks(runnable);
    }
}

在这个示例中，我们使用了MediaPlayer来播放音乐，使用SeekBar来显示进度条，使用Handler来更新SeekBar的进度。我们还添加了三个按钮，分别用于播放上一首、播放/暂停和播放下一首歌曲。在界面上，我们显示了歌曲的封面、标题、艺术家、专辑、当前时间和总时间。请注意，这个示例中使用的音乐文件是存储在`res/raw`目录下的一个示例文件。在实际应用中，您需要使用您自己的音乐文件。
