這篇文章主要為大家詳細(xì)介紹了android重力感應(yīng)開發(fā)之微信搖一搖功能，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下
本實例主要使用了android的重力感應(yīng)功能并配合動畫效果實現(xiàn)，主要代碼如下：

第二：一個檢測手機搖晃的監(jiān)聽器類ShakeListener ，代碼如下：
package com.android.shake;
import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.util.Log;
/**
* 一個檢測手機搖晃的監(jiān)聽器
*/
public class ShakeListener implements SensorEventListener {
// 速度閾值，當(dāng)搖晃速度達(dá)到這值后產(chǎn)生作用
private static final int SPEED_SHRESHOLD = 2000;
// 兩次檢測的時間間隔
private static final int UPTATE_INTERVAL_TIME = 70;
// 傳感器管理器
private SensorManager sensorManager;
// 傳感器
private Sensor sensor;
// 重力感應(yīng)監(jiān)聽器
private OnShakeListener onShakeListener;
// 上下文
private Context mContext;
// 手機上一個位置時重力感應(yīng)坐標(biāo)
private float lastX;
private float lastY;
private float lastZ;
// 上次檢測時間
private long lastUpdateTime;
// 構(gòu)造器
public ShakeListener(Context c) {
// 獲得監(jiān)聽對象
mContext = c;
start();
}
// 開始
public void start() {
// 獲得傳感器管理器
sensorManager = (SensorManager) mContext
.getSystemService(Context.SENSOR_SERVICE);
if (sensorManager != null) {
// 獲得重力傳感器
sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
}
// 注冊
if (sensor != null) {
sensorManager.registerListener(this, sensor,
SensorManager.SENSOR_DELAY_GAME);
}
}
// 停止檢測
public void stop() {
sensorManager.unregisterListener(this);
}
// 設(shè)置重力感應(yīng)監(jiān)聽器
public void setOnShakeListener(OnShakeListener listener) {
onShakeListener = listener;
}
// 重力感應(yīng)器感應(yīng)獲得變化數(shù)據(jù)
public void onSensorChanged(SensorEvent event) {
// 現(xiàn)在檢測時間
long currentUpdateTime = System.currentTimeMillis();
// 兩次檢測的時間間隔
long timeInterval = currentUpdateTime - lastUpdateTime;
// 判斷是否達(dá)到了檢測時間間隔
if (timeInterval < UPTATE_INTERVAL_TIME)
return;
// 現(xiàn)在的時間變成last時間
lastUpdateTime = currentUpdateTime;
// 獲得x,y,z坐標(biāo)
float x = event.values[0];
float y = event.values[1];
float z = event.values[2];
// 獲得x,y,z的變化值
float deltaX = x - lastX;
float deltaY = y - lastY;
float deltaZ = z - lastZ;
// 將現(xiàn)在的坐標(biāo)變成last坐標(biāo)
lastX = x;
lastY = y;
lastZ = z;
double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ
* deltaZ)
/ timeInterval * 10000;
// 達(dá)到速度閥值，發(fā)出提示
if (speed >= SPEED_SHRESHOLD) {
onShakeListener.onShake();
}
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
// 搖晃監(jiān)聽接口
public interface OnShakeListener {
public void onShake();
}
}

lastX = x;
lastY = y;
lastZ = z;
double speed = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ
* deltaZ)
/ timeInterval * 10000;
// 達(dá)到速度閥值，發(fā)出提示
if (speed >= SPEED_SHRESHOLD) {
onShakeListener.onShake();
}
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
// 搖晃監(jiān)聽接口
public interface OnShakeListener {
public void onShake();
}
}
第三：必須在AndroidManifest.xml中添加權(quán)限，否側(cè)搖動時不能監(jiān)聽
<uses-permission android:name="android.hardware.sensor.accelerometer"/>

Flutter 使用fluro的轉(zhuǎn)場動畫進(jìn)行頁面切換
在實際應(yīng)用中，我們常常會對不同的頁面采取不同的轉(zhuǎn)場動畫，以提高頁面切換過程中的用戶體驗。例如，微信的掃碼后在手機上確認(rèn)登錄頁面就是從底部彈出的，而大部分頁面的跳轉(zhuǎn)都是從右向左滑入。通過這種形式區(qū)分不同的轉(zhuǎn)場場景，從而給用戶更多的趣味性以提高用戶體驗。2021-06-06
