我有以下简单的 Android 应用程序。
package com.example.videotest;
public class MainActivity extends Activity {
private Button playButton;
private Button clearButton;
private Button stopButton;
private Button defaultButton;
private VideoView mVideoView;
private EditText editText;
private String videoAddress;
private static final String TAG = "videoTest";
private String keyValue = "videoAddress";
private String defaultAddress = "rtsp://v6.cache7.c.youtube.com/CjYLENy73wIaLQlpqssvHCj9nxMYDSANFEIJbXYtZ29vZ2xlSARSBXdhdGNoYLXw9ZeX2OLcUAw=/0/0/0/video.3gp";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
SharedPreferences prefs = this.getSharedPreferences(TAG, 0);
videoAddress = prefs.getString(keyValue, defaultAddress);
playButton = (Button)findViewById(R.id.button1);
clearButton = (Button)findViewById(R.id.button2);
stopButton = (Button)findViewById(R.id.button3);
defaultButton = (Button)findViewById(R.id.button4);
mVideoView = (VideoView) findViewById(R.id.videoView1);
editText = (EditText)findViewById(R.id.editText1);
editText.setText(videoAddress);
defaultButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
editText.setText(defaultAddress);
SharedPreferences appSettings = getSharedPreferences(TAG, 0);
SharedPreferences.Editor prefEditor = appSettings.edit();
prefEditor.putString(keyValue, defaultAddress);
prefEditor.commit();
}
});
stopButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
mVideoView.stopPlayback();
}
});
playButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
videoAddress = editText.getText().toString();
SharedPreferences appSettings = getSharedPreferences(TAG, 0);
SharedPreferences.Editor prefEditor = appSettings.edit();
prefEditor.putString(keyValue, videoAddress);
prefEditor.commit();
//PlayRtspStream("rtsp://10.0.0.32:5004/aac5.sdp");
PlayRtspStream(videoAddress);
}
});
clearButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
editText.setText("");
SharedPreferences appSettings = getSharedPreferences(TAG, 0);
SharedPreferences.Editor prefEditor = appSettings.edit();
prefEditor.putString(keyValue, "");
prefEditor.commit();
}
});
}
private void PlayRtspStream(String rtspUrl){
mVideoView.setVideoPath(rtspUrl);
//mVideoView.setVideoURI(Uri.parse(rtspUrl));
mVideoView.requestFocus();
mVideoView.start();
}
@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;
}
}
AndroidManifest.xml 文件

当我运行应用程序并将视频视图的视频路径设置为默认地址时，我收到提示“无法播放视频”。这是 logcat 文件。
