Question

我正在尝试从设备获取音频输入。在获取音频输入时，我尝试根据音频输入的强度将图标分配给标签。我使用以下代码：

public void run() {
        this.rec.startRecording();
        while (!this.done) {
            int nshorts = this.readBlock();
            if (nshorts <= 0)
                break;
        }
        //assignIcons();  
        this.rec.stop();
        this.rec.release();
    }

    int readBlock() {
        short[] buf = new short[this.block_size];

        int nshorts = this.rec.read(buf, 0, buf.length);
        if (nshorts > 0) {
            //Log.d(getClass().getName(), "Posting " + nshorts + " samples to queue");
            this.q.add(buf);
        }

        new Thread(new  Runnable() {
            public void run() {
                assignIcons(); 
            }
        }).start();
        return nshorts;
    }

    public void assignIcons(){
        //Add(Start)
        byte audioBuffer[]   = new  byte[this.minBufferSizeInBytes];//minBufferSizeInBytes = AudioRecord.getMinBufferSize( 8000,
                AudioFormat.CHANNEL_IN_MONO,AudioFormat.ENCODING_PCM_16BIT);
        float totalAbsValue = 0.0f;
        short sample = 0;
        int numberOfReadBytes = 0; 
        float tempFloatBuffer[] = new float[3];
        int tempIndex = 0;
        //Add(End)
      //Add(Start)
        numberOfReadBytes = this.rec.read( audioBuffer, 0, this.minBufferSizeInBytes );
        for( int i=0; i<numberOfReadBytes; i+=2 ) {
            sample = (short)( (audioBuffer[i]) | audioBuffer[i + 1] << 8 );
            if(sample!=0) {
                totalAbsValue += Math.abs( sample ) / (numberOfReadBytes/2);
            }
        }
        tempFloatBuffer[tempIndex%3] = totalAbsValue;
        temp = 0.0f;
        for( int i=0; i<3; ++i )
            temp += tempFloatBuffer[i];
        mCamBase = CameraBaseActivity.getInstance();
        mCamBase.handler.postDelayed(mCamBase.AnimateRunnable, 10);

        //Add(End)

    }

我遇到的问题是，我连续得到以下日志，但是我没有得到所需的输出。我确信我所显示的代码确实存在问题，但不确定导致所给出的日志连续输出的真正问题是什么。任何帮助解决这个问题都非常感谢。

obtainBuffer在AudioRecord - Android中超时
