我无法从具有webview的android应用程序播放mp3文件，我在其中调用html页面
这是我的主要活动档案
package com.example.dsspunjab;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
import android.webkit.WebView;
import android.widget.ImageButton;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity implements OnClickListener{
ImageButton button1, button2;
ImageButton button3;
WebView brows, brows1;
final Context context = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (ImageButton) findViewById(R.id.imageButton1);
button1.setOnClickListener(this);
button2 = (ImageButton) findViewById(R.id.imageButton2);
button2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
setContentView(R.layout.screen2);
button3 = (ImageButton) findViewById(R.id.button1);
brows1=(WebView) findViewById(R.id.webView1);
brows1.getSettings().setJavaScriptEnabled(true);
brows1.loadUrl("file:///android_asset/App1/index.html");
button3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, MainActivity.class);
startActivity(intent);
}
});
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public void onClick(View view) {
setContentView(R.layout.screen1);
button3 = (ImageButton) findViewById(R.id.button1);
brows=(WebView) findViewById(R.id.webView1);
brows.getSettings().setJavaScriptEnabled(true);
brows.loadUrl("file:///android_asset/App/index.html");
button3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(context, MainActivity.class);
startActivity(intent);
}
});
}
}
这是我调用mp3的html代码片段， ＆＃34;
<div class="modal-body">
<!-- <img src="images/paddy_varieties/click-detail-punjab-basmati-2.png" data-elem="pinchzoomer" alt="img1"/> -->
<audio msAudioCategory="BackgroundCapableMedia" controls="controls">
<source src="images/paddy_varieties/VN_Normal_1.mp3" class="mp3"/>
</audio>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-info" data-dismiss="modal">Close</button>
</div>
</div>
＆＃34;
我可以在通过网络浏览器浏览的html页面上播放视频（谷歌浏览器），但不能通过Android应用程序播放。
