Android 打开应用权限设置页面

1.首先判断自己的应用的通知权限是否开启

private static String CHECK_OP_NO_THROW = "checkOpNoThrow";
private static String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";

/**
* 判断该应用通知开关是否开启
* @param context
* @return
*/
@RequiresApi(api = Build.VERSION_CODES.KITKAT)//提高 Android 高版本的兼容
public static boolean isNotificationEnabled(Context context) {

AppOpsManager mAppOps = (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
ApplicationInfo appInfo = context.getApplicationInfo();
String pkg = context.getApplicationContext().getPackageName();//获取该应用信息
int uid = appInfo.uid;

Class appOpsClass = null;
try {
appOpsClass = Class.forName(AppOpsManager.class.getName());
Method checkOpNoThrowMethod = appOpsClass.getMethod(CHECK_OP_NO_THROW, Integer.TYPE, Integer.TYPE,
String.class);
Field opPostNotificationValue = appOpsClass.getDeclaredField(OP_POST_NOTIFICATION);

int value = (Integer) opPostNotificationValue.get(Integer.class);
//根据信息得到值进行比较 如果相等则返回true 否则返回false
 return ((Integer) checkOpNoThrowMethod.invoke(mAppOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED);

} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
return false;
}
2.调起系统自带 Dialog 去处理

/**
* 判断手机通知是否开启，没有开启则打开应用管理权限页面
* @param context
*/
public static void showDelDialog(final Context context){
// 构造对话框
AlertDialog.Builder builder = new AlertDialog.Builder(context);//构建一个AlertDialog.Builder对象
builder.setTitle("温馨提示");//设置标题

builder.setIcon(R.drawable.ic_app);//设置图标

builder.setMessage("你推送功能尚未开启，会影响您的正常使用，请开启推送功能");//设置提示内容
//创建两个点击事件
 // 更新 builder.setPositiveButton("确认打开", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) {
//根据包名打开对应的应用权限设置页面
 dialog.dismiss(); Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);//设置去向意图 Uri uri = Uri.fromParts("package", context.getPackageName(), null); intent.setData(uri);
//发起跳转
 context.startActivity(intent); } }); // 稍后更新 builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) {
  //关闭对话框
dialog.dismiss(); } }); Dialog noticeDialog = builder.create(); noticeDialog.setCanceledOnTouchOutside(false); noticeDialog.setCancelable(false); noticeDialog.show();}
