android系统传感器获取

1显示系统获取的传感器的布局文件activity_main.xml

xmlns:tools="/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"

android:id="@+id/tips_tv"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/hello_world"/>

android:id="@+id/scrollView1"

android:layout_below="@+id/tips_tv"

android:layout_height="wrap_content">

android:id="@+id/all_ll"

2获取系统的传感器：

setContentView(yout.activity_main);

all_ll=(LinearLayout)findViewById(R.id.all_ll);

tips_tv=(TextView)findViewById(R.id.tips_tv);

SensorManager sensorManager=(SensorManager)getSystemService(Contex

t.SENSOR_SERVICE);

Listsensors=sensorManager.getSensorList(Sensor.TYPE_ALL);

tips_tv.setText("传感器的个数："+ sensors.size());

for (Sensor s :sensors) {

Button bt=new Button(this);

bt.setText(getSensorName(s.getType()));

bt.setId(s.getType());

bt.setOnClickListener(this);

all_ll.addView(bt);

}

3根据传感器类型获取传感器的名称

private String getSensorName(int type){

String name="";

switch (type) {

case Sensor.TYPE_ACCELEROMETER:

name="重力加速度感测器";

break;
