使用Achartengine绘制显示ANR的加速度计数据

标签： android achartengine android-anr-dialog

我正在使用achartengine for android来绘制Acclerometer数据。 但是，一旦启动活动，应用程序就会挂起并在一段时间后显示ANR。 请有人告诉我哪里出错了。 这是我的代码。

    public class TestButtonActivity extends Activity implements
    SensorEventListener{

private LinearLayout lyGforce;
private SensorManager mSensorManager;
private Sensor mAccelerometer;
private TimeSeries timeSeriesGforcex;
private TimeSeries timeSeriesGforcey;
private TimeSeries timeSeriesGforcez;
private XYMultipleSeriesDataset datasetGforce;
private XYMultipleSeriesRenderer rendererGforce;
private XYSeriesRenderer rendererSeriesGforce;
private XYSeriesRenderer rendererSeriesGforcey;
private XYSeriesRenderer rendererSeriesGforcez;
private GraphicalView viewGforce;
Handler h;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_test_button);
    Log.e("", "deepak");
    h = new Handler();
    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    mAccelerometer = mSensorManager
            .getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    mSensorManager.registerListener(this, mAccelerometer,
    SensorManager.SENSOR_DELAY_UI);

    datasetGforce = new XYMultipleSeriesDataset();
    rendererGforce = new XYMultipleSeriesRenderer();
    rendererGforce.setApplyBackgroundColor(true);
    rendererGforce.setBackgroundColor(Color.argb(100, 50, 50, 50));
    rendererGforce.setAxisTitleTextSize(16);
    rendererGforce.setChartTitleTextSize(20);
    rendererGforce.setLabelsTextSize(15);
    rendererGforce.setLegendTextSize(15);
    rendererGforce.setMargins(new int[] { 20, 30, 15, 20 });
    // rendererGforce.setZoomButtonsVisible(true);

    rendererGforce.setPointSize(10);
    rendererGforce.setShowGrid(true);
    rendererGforce.setGridColor(Color.WHITE);

    rendererSeriesGforce = new XYSeriesRenderer();
    rendererSeriesGforce.setColor(Color.GREEN);
    rendererSeriesGforce.setLineWidth(2);

    rendererSeriesGforcey = new XYSeriesRenderer();
    rendererSeriesGforcey.setColor(Color.RED);
    rendererSeriesGforcey.setLineWidth(2);

    rendererSeriesGforcez = new XYSeriesRenderer();
    rendererSeriesGforcez.setColor(Color.BLUE);
    rendererSeriesGforcez.setLineWidth(2);

    rendererGforce.addSeriesRenderer(rendererSeriesGforce);
    rendererGforce.addSeriesRenderer(rendererSeriesGforcey);
    rendererGforce.addSeriesRenderer(rendererSeriesGforcez);

    timeSeriesGforcex = new TimeSeries("x");
    timeSeriesGforcey = new TimeSeries("y");
    timeSeriesGforcez = new TimeSeries("z");

    datasetGforce.addSeries(timeSeriesGforcex);
    datasetGforce.addSeries(timeSeriesGforcey);
    datasetGforce.addSeries(timeSeriesGforcez);

    viewGforce = ChartFactory.getTimeChartView(this, datasetGforce,
            rendererGforce, "");
    viewGforce.refreshDrawableState();
    viewGforce.repaint();
    lyGforce = (LinearLayout) findViewById(R.id.graph_view_container);
    lyGforce.addView(viewGforce);
    viewGforce.refreshDrawableState();
    viewGforce.repaint();

}

@Override
protected void onResume() {
    super.onResume();

}

@Override
protected void onPause() {
    Log.d("onPause", "onPause");
    mSensorManager.unregisterListener(this);
    super.onPause();
}

@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {


}

@Override
public void onSensorChanged(SensorEvent event) {
    float x = event.values[0];
    float y = event.values[1];
    float z = event.values[2];
    Log.d("", "" + x + "" + y + "" + z);

    timeSeriesGforcex.add(new Date(), x);
    timeSeriesGforcey.add(new Date(), y);
    timeSeriesGforcez.add(new Date(), z);

    rendererGforce.setXAxisMax(rendererGforce.getXAxisMax() + 100);
    rendererGforce.setXAxisMin(rendererGforce.getXAxisMin() + 30);
    viewGforce.repaint();
}}

这就是logcat所说的：

1 个答案:

答案 0 :(得分：1)

终于找到了。

    rendererGforce.setShowGrid(true);

onCreate（）中的这句话是罪魁祸首。 从onCreate（）中注释掉它，并在viewGforce.repaint（）之前添加到onSensorChanged（）;它会完美无缺。

确保在onPause（）中将其设置为false。

有一天可能会拯救某人的时间。
