1、摇一摇Listener

// 传感器管理器

private SensorManager sensorManager;

// 传感器

2、摇一摇主界面Activity

} catch (Exception e) {

Toast.makeText(YaoYiYaoActivity.this, e.getMessage(),

Toast.LENGTH_SHORT).show();

}

}

});

}

 

///**

/**

* 获取经度维度

*/

public Location getLocation() {

// 获取到LocationManager对象

// 创建一个Criteria对象

Criteria criteria = new Criteria();

// 设置粗略精确度

criteria.setAccuracy(Criteria.ACCURACY_COARSE);

// 设置是否需要返回海拔信息

criteria.setAltitudeRequired(false);

// 设置是否需要返回方位信息

criteria.setBearingRequired(false);

// 设置是否允许付费服务

criteria.setCostAllowed(true);

// 设置电量消耗等级

// 根据设置的Criteria对象，获取最符合此标准的provider对象

String currentProvider = locationManager

}

.getLastKnownLocation(currentProvider);

if (currentLocation == null) {

locationManager.requestLocationUpdates(currentProvider, 0, 0,

locationListener);

}

// 直到获得最后一次位置信息为止，如果未获得最后一次位置信息，则显示默认经纬度

// 每隔3秒获取一次位置信息

while (true) {

currentLocation = locationManager

.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

if (currentLocation != null) {

Log.e("Location", "Latitude: " + currentLocation.getLatitude());

Log.e("Location",

}

}

 

/**

@Override

protected void onDestroy() {

super.onDestroy();

if (mShakeListener != null) {

mShakeListener.stop();

}

}

3、摇一摇主界面shake.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

 

    <TextView

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_gravity="center_vertical"

        android:gravity="center_vertical|center_horizontal"

        android:text="摇一摇"

        android:textColor="#3A7EBD"

        android:textSize="36dp" />

 

    <ImageView

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:src="@drawable/shake" />

</LinearLayout>

4、摇一摇跳转Activity

package com.tangzq;

 

import android.app.Activity;

import android.graphics.Color;

import android.os.Bundle;

import android.view.Gravity;

import android.widget.TextView;

 

public class AfterShakedActivity extends Activity{

 

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

TextView tv=new TextView(this);

tv.setText("哈哈，你摇成功了，xiangxi信息");

tv.setBackgroundDrawable(getResources().getDrawable(R.drawable.smile));

tv.setTextSize(32);

tv.setTextColor(Color.MAGENTA);

//tv.setGravity(Gravity.CENTER_VERTICAL|Gravity.CENTER_HORIZONTAL);

tv.setGravity(Gravity.CENTER_HORIZONTAL);

//tv.setGravity();

setContentView(tv);

}

}
