1、addView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="36dp"
android:text="@string/hello_world" />
<TextView
android:id="@+id/tv_two"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="@+id/textView1" />
</RelativeLayout>
2 使用代码，
package com.example.gsensorapp;
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 MainActivity extends Activity implements SensorEventListener {
private SensorManager mSensorManager;
private Sensor mAccelerometer;
private TextView mTextView;
private TextView mTextViewHello;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE); //传感器管理器获取到 SensorManager 的实例
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); //获取传感器类型
mTextView =(TextView)this.findViewById(R.id.tv_two); //获取Text view
mTextViewHello =(TextView)this.findViewById(R.id.textView1);
}
protected void onResume() { //加速度传感器注册监听器
super.onResume();
mSensorManager.registerListener((SensorEventListener) this, mAccelerometer,SensorManager.SENSOR_DELAY_NORMAL);
mTextViewHello.setText("Accelerometer test hello"); //在模拟器上测试
}
protected void onPause() { //取消注册监听器
super.onPause();
mSensorManager.unregisterListener((SensorEventListener) this);
}
public void onAccuracyChanged(Sensor sensor, int accuracy) { //传感器的精度发生变化时就会调用
}
public void onSensorChanged(SensorEvent event) { //当传感器监测到的数值发生变化时就会调用
float[] values = event.values;
//TextView mTextView=new TextView(this);
mTextView.setText("Accelerometer:" + values[0] + ";" + values[1] + ";" + values[2]); //显示
}
}
3：生成的apk放项目下编译加签名。
include $(CLEAR_VARS)
# Module name should match apk name to be installed
LOCAL_MODULE := Gsensorapp
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)
adb push system/app/目录中
4：图片效果
5:直接用eclipse中DDMS连接硬件设备，我连接的是我我自己编译的系统。
然后用Screen Capture 功能拍照
