android - 如何在Android Studio中设置库

我正在尝试设置waveInApp库http://www.materialup.com/posts/waveinapp
我已经声明了所有必需的东西。
 工作，但背景wave不起作用。我无法将wave功能设置为android开发中的初学者。
我能够设置所有基本内容，包括媒体播放器。
在这里我无法设置语音识别处理程序
这是我所做的

import android.content.Context;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;
import com.cleveroad.audiovisualization.AudioVisualization;
import com.cleveroad.audiovisualization.DbmHandler;
import com.cleveroad.audiovisualization.SpeechRecognizerDbmHandler;
import com.cleveroad.audiovisualization.VisualizerDbmHandler;

public class MainActivity extends AppCompatActivity {
private AudioVisualization audioVisualization;
private Context context;
private ImageButton button1,button2;
private MediaPlayer mediaPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    audioVisualization = (AudioVisualization)findViewById(R.id.visualizer_view);
    button1=(ImageButton)findViewById(R.id.imageButton);
    button2=(ImageButton)findViewById(R.id.imageButton2);
    mediaPlayer =MediaPlayer.create(this,R.raw.song);

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getApplicationContext(),"playing",Toast.LENGTH_SHORT).show();
            mediaPlayer.start();
        }
    });
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    Toast.makeText(getApplicationContext(),"pause",Toast.LENGTH_SHORT).show();
    mediaPlayer.pause();
    VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
    audioVisualization.linkTo(vizualizerHandler);
    // set speech recognizer handler
    SpeechRecognizerDbmHandler speechRecHandler = DbmHandler.Factory.newSpeechRecognizerHandler(context);
    speechRecHandler.innerRecognitionListener(...);
    audioVisualization.linkTo(speechRecHandler);
}
});
}

@Override
public void onResume() {
    super.onResume();
    audioVisualization.onResume();
}

@Override
public void onPause() {
    audioVisualization.onPause();
    super.onPause();
}
 }

那么如何设置上述handeler。我无法将连接音频可视化视图设置为音频输出。如何使用媒体播放器设置以下方法

// set speech recognizer handler
SpeechRecognizerDbmHandler speechRecHandler = DbmHandler.Factory.newSpeechRecognizerHandler(context);
speechRecHandler.innerRecognitionListener(...);
audioVisualization.linkTo(speechRecHandler);

// set audio visualization handler. This will REPLACE previously set speech recognizer handler
VisualizerDbmHandler vizualizerHandler = DbmHandler.Factory.newVisualizerHandler(getContext(), 0);
audioVisualization.linkTo(vizualizerHandler);

除此之外，所有提示或建议都将有所帮助。

那么有人可以告诉我为什么使用片段以及如何在主要活动中设置它吗？

最佳答案

I know i am late to post this answer...but for future use try this
check my code you will find your answer
first of all in the liberay you have to make some changes in your xml.


<com.cleveroad.audiovisualization.GLAudioVisualizationView
    android:id="@+id/visualizer_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:av_bubblesSize= "@dimen/bubble_size"
    app:av_bubblesRandomizeSizes= "true"
    app:av_wavesHeight= "@dimen/wave_height"
    app:av_wavesFooterHeight="@dimen/footer_height"
    app:av_wavesCount="7"
    app:av_layersCount="4" />

然后

  private VisualizerDbmHandler handler;
  MediaPlayer mp ;
  private AudioVisualization audioVisualization;

  public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View ve = inflater.inflate(R.layout.cat, container, false);
    ibCapture = (ImageButton) ve.findViewById(R.id.ibCapture);
    audioVisualization =  (AudioVisualization)ve.findViewById(R.id.visualizer_view);
   hell();
    return ve;
}



    ibCapture.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            if (bool) {
                bool = false;
                mp = MediaPlayer.create(getContext(), R.raw.blackcat);
                mp.setLooping(true);
                handler = VisualizerDbmHandler.Factory.newVisualizerHandler(getContext(),mp);
                audioVisualization.linkTo(handler);
                mp.start();

            ((home)getActivity()).vis();
            } else {
                bool = true;
                ((home)getActivity()).visgone();
                stopPlaying();
            }
        }
    });
