我希望在 Actvity 中显示有关传感器的详细信息，但是当我将应用程序放入手机时，我设法仅查看有关加速度计的详细信息，但程序说我有 4 个传感器：加速度计、磁场、方向和温度.

我正在使用 Android 1.6 和 htc Tattoo 进行测试。

这是我的代码： public class SensorInfo extends Activity { private SensorManager mSensorManager; TextView mTextAcc,mTextGyr,mTextLig,mTextMag,mTextOri, mTextPre,mTextPro,mTextTem, mSensorsTotTitle,mSensorAvailablesTitle,mTextAccTitle,mTextGyrTitle,mTextLigTitle,mTextMagTitle,mTextOriTitle, mTextPreTitle,mTextProTitle,mTextTemTitle; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.detaillayout); // Get the texts fields of the layout and setup to invisible setTextViews();

    // Get the SensorManager 
    mSensorManager= (SensorManager) getSystemService(SENSOR_SERVICE);

    // List of Sensors Available
    List<Sensor> msensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL);

    // Print Sensor Details
    Sensor sens;
    int type,i;
    String text = new String("");
    // Do the list of available sensors on a String and print detail about each sensor
    for (i=0;i<msensorList.size();i++){
        sens = msensorList.get(i);
        type    = sens.getType();
        text = " - "+getString(R.string.power)+" "+String.valueOf(sens.getPower())+"mA\n";
        text+= " - "+getString(R.string.resolution)+" "+String.valueOf(sens.getResolution())+"\n";
        text+= " - "+getString(R.string.maxrange)+" "+String.valueOf(sens.getMaximumRange ())+"\n";
        text+= " - "+getString(R.string.vendor)+" "+sens.getVendor()+"\n";
        text+= " - "+getString(R.string.version)+" "+String.valueOf(sens.getVersion());
        switch(type) {      // Check the type of Sensor that generate the event and show is resolution

已解决，我只将默认传感器注册到 de sensorListener，而我必须分别注册每个传感器！

这是最终代码：

public class SensorInfo extends Activity {
private SensorManager mSensorManager;
TextView mTextAcc,mTextGyr,mTextLig,mTextMag,mTextOri,
 mTextPre,mTextPro,mTextTem,
 mSensorsTotTitle,mSensorAvailablesTitle,mTextAccTitle,mTextGyrTitle,mTextLigTitle,mTextMagTitle,mTextOriTitle,
 mTextPreTitle,mTextProTitle,mTextTemTitle;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.detaillayout);
    // Get the texts fields of the layout and setup to invisible
    setTextViews();

    // Get the SensorManager 
    mSensorManager= (SensorManager) getSystemService(SENSOR_SERVICE);

    // List of Sensors Available
    List<Sensor> msensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL);

    // Print Sensor Details
    Sensor sens;
    int type,i;
    String text = new String("");
    // Do the list of available sensors on a String and print detail about each sensor
    for (i=0;i<msensorList.size();i++){
        sens = msensorList.get(i);
        type    = sens.getType();
        text = " - "+getString(R.string.power)+" "+String.valueOf(sens.getPower())+"mA\n";
        text+= " - "+getString(R.string.resolution)+" "+String.valueOf(sens.getResolution())+"\n";
        text+= " - "+getString(R.string.maxrange)+" "+String.valueOf(sens.getMaximumRange ())+"\n";
        text+= " - "+getString(R.string.vendor)+" "+sens.getVendor()+"\n";
