Android的音频搜索栏 [英] Android Audio SeekBar
本文介绍了Android的音频搜索栏的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想创造的东西在一个单一的音频文件播放，可暂停和操纵带有进度/搜索栏。我想有一个图像占用大部分屏幕，然后在底部的播放暂停按钮左和杆的按钮的右侧。一切正常，未链接到音频的搜索栏。我的进度条编码是一种可能，因为如果从几个拍摄它，我已经看到了在互联网上一片狼藉，但他们大多是困惑我，因为他们是音乐播放器应用程式不适合打单的音频文件。
可能有人请帮助我的进度条？对提高我的编程其他任何提示将是巨大的。

解决方案
我觉得这可以为你的工作。
创建一个线程，将检查首歌位置，将移动搜索栏这样的，
私人的Runnable moveSeekBarThread =新的Runnable（）{ 公共无效的run（）{
如果（mediaPlayer.isplaying）{ INT mediaPos_new = mediaPlayer.getCurrentPosition（）;
INT mediaMax_new = mediaPlayer.getDuration（）;
seekBar.setMax（mediaMax_new）;
seekBar.setProgress（mediaPos_new）; handler.postDelayed（此，100）; //循环线程0.1秒后
//秒
}
}
};
并调用线程这样，
mediaPos = mediaPlayer.getCurrentPosition（）;
mediaMax = mediaPlayer.getDuration（）; seekBar.setMax（mediaMax）; //设置的最大范围
seekBar.setProgress（mediaPos）; //设置当前的进度，这首歌的 handler.removeCallbacks（moveSeekBarThread）;
handler.postDelayed（moveSeekBarThread，100）;
I'm trying to create something where a single audio file is played and can be paused and manipulated with a progress/seek bar. I want to have an image taking up most of the screen and then a play pause button on the bottom left and the bar to the right of the button. Everything works the seekbar which isn't link to the audio. My progress bar coding is a probably a mess because if taken it from several i've seen on the internet but they are mostly confusing for me as they are for music player apps not for playing a single audio file.
Could someone please help me with the progress bar? Any other tips on improving my programming would be great too.
(I am very new to android and programming just to warn you)
This is my Java:
MediaPlayer mediaPlayer;
Button buttonPlayPause;
ImageView Image;
SeekBar seekBar;
private int stateMediaPlayer;
private final int stateMP_NotStarter = 0;
private final int stateMP_Playing = 1;
private final int stateMP_Pausing = 2;
int total;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playerwere);
Image = (ImageView) findViewById(R.id.pdfview);
Image.setImageResource(R.drawable.wereim);
seekBar = (SeekBar) findViewById(R.id.seekBar);
buttonPlayPause = (Button) findViewById(R.id.playpause);
buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);
seekBar.setOnSeekBarChangeListener(seekBarOnSeekListener);
initMediaPlayer();
Thread currentThread = new Thread(this);
currentThread.start();
}
private void initMediaPlayer() {
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
stateMediaPlayer = stateMP_NotStarter;
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer arg0) {
// TODO Auto-generated method stub
total = mediaPlayer.getDuration();
}
});
seekBar.setProgress(0);
seekBar.setMax(total);
}
Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (stateMediaPlayer) {
case stateMP_NotStarter:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
case stateMP_Playing:
mediaPlayer.pause();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
stateMediaPlayer = stateMP_Pausing;
break;
case stateMP_Pausing:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
}
}
};
SeekBar.OnSeekBarChangeListener seekBarOnSeekListener = new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// TODO Auto-generated method stub
if (fromUser) {
mediaPlayer.seekTo(progress);
seekBar.setProgress(progress);
}
}
};
@Override
public void run() {
// TODO Auto-generated method stub
try {
while (mediaPlayer != null) {
int currentPosition = mediaPlayer.getCurrentPosition();
Message msg = new Message();
msg.what = currentPosition;
threadHandler.sendMessage(msg);
}
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
private Handler threadHandler = new Handler() {
public void handleMessage(Message msg) {
seekBar.setProgress(msg.what);
}
};
And this is what my java was before i tried to use the seekBar:
MediaPlayer mediaPlayer;
Button buttonPlayPause;
ImageView Image;
private int stateMediaPlayer;
private final int stateMP_NotStarter = 0;
private final int stateMP_Playing = 1;
private final int stateMP_Pausing = 2;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playerwere);
Image = (ImageView) findViewById(R.id.pdfview);
Image.setImageResource(R.drawable.wereim);
buttonPlayPause = (Button) findViewById(R.id.playpause);
buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);
initMediaPlayer();
}
private void initMediaPlayer() {
mediaPlayer = new MediaPlayer();
mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
stateMediaPlayer = stateMP_NotStarter;
}
Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (stateMediaPlayer) {
case stateMP_NotStarter:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
case stateMP_Playing:
mediaPlayer.pause();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
stateMediaPlayer = stateMP_Pausing;
break;
case stateMP_Pausing:
mediaPlayer.start();
buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
stateMediaPlayer = stateMP_Playing;
break;
}
}
};
This is my java after Vishal Vaja's answer:
MediaPlayer mediaPlayer;
Button buttonPlayPause;

buttonPlayPause = (Button) findViewById(R.id.playpause);
buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);
seekBar.setOnSeekBarChangeListener(seekBarOnSeekChangeListener);
initMediaPlayer();
}
private void initMediaPlayer() {

seekBar.setMax(mediaMax_new);

boolean fromUser) {

if (fromUser) {
mediaPlayer.seekTo(progress);
seekBar.setProgress(progress);
}
}
};
解决方案
I think this can be work for you.
Create one thread that will check song position and will move seekbar like this,
private Runnable moveSeekBarThread = new Runnable() {
public void run() {
if(mediaPlayer.isplaying){
int mediaPos_new = mediaPlayer.getCurrentPosition();
int mediaMax_new = mediaPlayer.getDuration();
seekBar.setMax(mediaMax_new);
seekBar.setProgress(mediaPos_new);
handler.postDelayed(this, 100); //Looping the thread after 0.1 second
// seconds
}
}
};
And call that thread like this,
mediaPos = mediaPlayer.getCurrentPosition();
mediaMax = mediaPlayer.getDuration();
seekBar.setMax(mediaMax); // Set the Maximum range of the
seekBar.setProgress(mediaPos);// set current progress to song's
handler.removeCallbacks(moveSeekBarThread);
handler.postDelayed(moveSeekBarThread, 100);
