撥打電話
public static void call(Context context, String phoneNumber) {
context.startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber)));
}
跳轉至撥號界面
public static void callDial(Context context, String phoneNumber) {
context.startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + phoneNumber)));
}
發送短信
public static void sendSms(Context context, String phoneNumber,
String content) {
Uri uri = Uri.parse("smsto:"
+ (TextUtils.isEmpty(phoneNumber) ? "" : phoneNumber));
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", TextUtils.isEmpty(content) ? "" : content);
context.startActivity(intent);
}
喚醒屏幕並解鎖
public static void wakeUpAndUnlock(Context context){
KeyguardManager km= (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
//解鎖
kl.disableKeyguard();
//獲取電源管理器對象
PowerManager pm=(PowerManager) context.getSystemService(Context.POWER_SERVICE);
//獲取PowerManager.WakeLock對象,後面的參數|表示同時傳入兩個值,最後的是LogCat裏用的Tag
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK,"bright");
//點亮屏幕
wl.acquire();
//釋放
wl.release();
}
需要添加權限<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
判斷當前App處於前臺還是後臺狀態
public static boolean isApplicationBackground(final Context context) {
ActivityManager am = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
@SuppressWarnings("deprecation")
List<ActivityManager.RunningTaskInfo> tasks = am.getRunningTasks(1);
if (!tasks.isEmpty()) {
ComponentName topActivity = tasks.get(0).topActivity;
if (!topActivity.getPackageName().equals(context.getPackageName())) {
return true;
}
}
return false;
}
需要添加權限
<code class="hljs xml has-numbering"><span class="hljs-tag"><<span class="hljs-title">uses-permission </span> <span class="hljs-attribute">android:name</span>=<span class="hljs-value">"android.permission.GET_TASKS"</span> /></span></code>
判斷當前手機是否處於鎖屏(睡眠)狀態
public static boolean isSleeping(Context context) {
KeyguardManager kgMgr = (KeyguardManager) context
.getSystemService(Context.KEYGUARD_SERVICE);
boolean isSleeping = kgMgr.inKeyguardRestrictedInputMode();
return isSleeping;
}
判斷當前是否有網絡連接
public static boolean isOnline(Context context) {
ConnectivityManager manager = (ConnectivityManager) context
.getSystemService(Activity.CONNECTIVITY_SERVICE);
NetworkInfo info = manager.getActiveNetworkInfo();
if (info != null && info.isConnected()) {
return true;
}
return false;
}
判斷當前是否是WIFI連接狀態
public static boolean isWifiConnected(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo wifiNetworkInfo = connectivityManager
.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
if (wifiNetworkInfo.isConnected()) {
return true;
}
return false;
}
安裝APK
public static void installApk(Context context, File file) {
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.setType("application/vnd.android.package-archive");
intent.setDataAndType(Uri.fromFile(file),
"application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
}
判斷當前設備是否爲手機
public static boolean isPhone(Context context) {
TelephonyManager telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
if (telephony.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE) {
return false;
} else {
return true;
}
}
獲取當前設備寬高,單位px
@SuppressWarnings("deprecation")
public static int getDeviceWidth(Context context) {
WindowManager manager = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
return manager.getDefaultDisplay().getWidth();
}
@SuppressWarnings("deprecation")
public static int getDeviceHeight(Context context) {
WindowManager manager = (WindowManager) context
.getSystemService(Context.WINDOW_SERVICE);
return manager.getDefaultDisplay().getHeight();
}
獲取當前設備的IMEI,需要與上面的isPhone()一起使用
@TargetApi(Build.VERSION_CODES.CUPCAKE)
public static String getDeviceIMEI(Context context) {
String deviceId;
if (isPhone(context)) {
TelephonyManager telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
deviceId = telephony.getDeviceId();
} else {
deviceId = Settings.Secure.getString(context.getContentResolver(),
Settings.Secure.ANDROID_ID);
}
return deviceId;
}
獲取當前設備的MAC地址
public static String getMacAddress(Context context) {
String macAddress;
WifiManager wifi = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
WifiInfo info = wifi.getConnectionInfo();
macAddress = info.getMacAddress();
if (null == macAddress) {
return "";
}
macAddress = macAddress.replace(":", "");
return macAddress;
}
..
獲取當前程序的版本號
public static String getAppVersion(Context context) {
String version = "0";
try {
version = context.getPackageManager().getPackageInfo(
context.getPackageName(), 0).versionName;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return version;
}
