Android模拟器学framework和driver之传感器篇4（Android APP）

上面已经介绍了，android temperature sensor的移植过程，代码页已经贴给大家了，现在我们写一个APK来进行测试，代码很简单，界面也很简单很丑陋，哈哈，大家不要介意，这个aok只是用作测试，这里我就不多做介绍了，直接贴代码。

package com.android.jay.sensor1;

import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;

public class MySensor1Activity extends Activity implements SensorEventListener {
    /** Called when the activity is first created. */
    private TextView tView;
    SensorManager sensorManager = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tView=(TextView)findViewById(R.id.tv);
        sensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
        sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_TEMPERATURE),sensorManager.SENSOR_DELAY_GAME);
    }

    public void onSensorChanged(SensorEvent event) {
        if(event.sensor.getType()==Sensor.TYPE_TEMPERATURE)
            tView.setText("value: "+Float.toString(event.values[0]));

    }

    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        // TODO Auto-generated method stub

    }
}
package com.android.jay.sensor1;

import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;

public class MySensor1Activity extends Activity implements SensorEventListener {
    /** Called when the activity is first created. */
       private TextView tView;
       SensorManager sensorManager = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tView=(TextView)findViewById(R.id.tv);
        sensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
        sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_TEMPERATURE),sensorManager.SENSOR_DELAY_GAME);
    }

    public void onSensorChanged(SensorEvent event) {
           if(event.sensor.getType()==Sensor.TYPE_TEMPERATURE)
                  tView.setText("value: "+Float.toString(event.values[0]));

       }

       public void onAccuracyChanged(Sensor sensor, int accuracy) {
              // TODO Auto-generated method stub

       }
}
最后用adb install xxx.apk安装程序，然后再模拟器上运行，结果如下：

OK，看到value在不断的变化了吧，完工，下面一节我们会介绍framework层如何处理的。。。
