我试图做一个简单的在线广播播放器。这是流媒体的地址:http://radio-electron.ru:8000/96 这是我的代码。
MyActivity.java
package com.example.untitled2;
import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import java.io.IOException;
public class MyActivity extends Activity {
MediaPlayer mediaPlayer;
Button playButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onStart() {
super.onStart();
}
@Override
public void onResume() {
super.onResume();
mediaPlayer = new MediaPlayer();
playButton = (Button)findViewById(R.id.button);
playButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(mediaPlayer.isPlaying())
mediaPlayer.stop();
else {
try {
mediaPlayer.setDataSource(getApplicationContext(), Uri.parse("http://radio-electron.ru:8000/96"));
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
@Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i2) {
Toast.makeText(getApplicationContext(), "ERROR " + i, Toast.LENGTH_LONG).show();
playButton.setEnabled(false);
Log.d("radio", "error " + i + " " + i2);
return false; //To change body of implemented methods use File | Settings | File Templates.
}
});
mediaPlayer.prepareAsync();
}
catch (IOException e) {
Toast.makeText(getApplicationContext(), "ERROR " + e, Toast.LENGTH_LONG).show();
Log.d("radio", "error " + e);
}
mediaPlayer.start();
}
}
});
}
}
主要.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/button"
android:layout_gravity="center"/>
</FrameLayout>
我不知道为什么会出现-(38, 0)的代码,也不知道它是什么意思。我正在使用Intellij IDEA,在Android 2.3和4.2模拟器上尝试运行这段代码,但遇到了一些问题。
