android - 如何在android studio中设置库

Question

我正在尝试设置一个 waveInApp 库 http://www.materialup.com/posts/waveinapp我已经声明了所有必需的东西。应用程序 工作但背景波不工作。我无法将波函数设置为 android 开发的初学者。我能够设置所有基本的东西，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();
}
 }

那么如何设置上面的handeler。我无法将连接音频可视化 View 设置为音频输出。如何用媒体播放器设置如下方法

// 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);

除此之外一切正常。任何提示或建议都会有所帮助。我试着搜索

来自 https://github.com/Cleveroad/WaveInApp/blob/master/app/src/main/java/com/cleveroad/example/SpeechRecognitionFragment.java那么有人可以告诉我为什么使用 fragment 以及如何在我的主要 Activity 中设置它吗？

Answer 1

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();
            }
        }
    });
