android开发(27) 看看我的手机里都有什么传感器

想看看我的HTC ONE x 具有什么传感器。写个代码RUN一下。

代码很简单，直接贴了

package zyf.demo.sensordemo;

import java.util.List;

import android.hardware.Sensor;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {
    TextView tx1 = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tx1 = (TextView) findViewById(R.id.txt);
        showIt();
    }

    public void showIt() {
        //获得传感器管理器
        SensorManager sm = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
        List<Sensor> allSensors = sm.getSensorList(Sensor.TYPE_ALL);

        StringBuilder sb = new StringBuilder();
        // 显示有多少个传感器
        sb.append("\t该手机有" + allSensors.size() + "个传感器：\n\n");

        String typeName = "";
        // 显示每个传感器的具体信息
        for (Sensor s : allSensors) {
            typeName = SensorTypeName.getSensorTypeName(s.getType());
            sb.append(String.format("\t类型:%s\n", typeName));
            sb.append(String.format("\t设备名称:%s\n", s.getName()));
            sb.append(String.format("\t设备版本:%s\n", s.getVersion()));
            sb.append(String.format("\t供应商:%s\n", s.getVendor()));
            sb.append("\n");
        }// end for

        tx1.setText(sb.toString());
    }

    static class SensorTypeName {
        private static String[] itsNames;

        static {
            itsNames = new String[20];
            itsNames[0] = "未知";
            itsNames[Sensor.TYPE_ACCELEROMETER] = "加速度";
            itsNames[Sensor.TYPE_MAGNETIC_FIELD] = "磁力";
            itsNames[Sensor.TYPE_ORIENTATION] = "方向";
            itsNames[Sensor.TYPE_GYROSCOPE] = "陀螺仪";
            itsNames[Sensor.TYPE_LIGHT] = "光线感应";
            itsNames[Sensor.TYPE_PRESSURE] = "压力";
            itsNames[Sensor.TYPE_TEMPERATURE] = "温度";
            itsNames[Sensor.TYPE_PROXIMITY] = "接近,距离传感器";
            itsNames[Sensor.TYPE_GRAVITY] = "重力";
            itsNames[Sensor.TYPE_LINEAR_ACCELERATION] = "线性加速度";
            itsNames[Sensor.TYPE_ROTATION_VECTOR] = "旋转矢量";
            itsNames[Sensor.TYPE_RELATIVE_HUMIDITY] = "TYPE_RELATIVE_HUMIDITY";
            itsNames[Sensor.TYPE_AMBIENT_TEMPERATURE] = "TYPE_AMBIENT_TEMPERATURE";
            itsNames[13] = "TYPE_AMBIENT_TEMPERATURE";
            itsNames[14] = "TYPE_MAGNETIC_FIELD_UNCALIBRATED";
            //itsNames[Sensor.TYPE_GAME_ROTATION_VECTOR] = "TYPE_GAME_ROTATION_VECTOR";
        }

        public static String getSensorTypeName(int type){
            if(type > 0 && type < itsNames.length){
                return itsNames[type];
            }
            return "未知";
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}
