Android判断app是否打开消息通知并跳转设置

1、判断是否打开

NotificationManagerCompat notification = NotificationManagerCompat.from(this);
boolean isEnabled = notification.areNotificationsEnabled();

2、跳转系统设置

public static final String SETTINGS_ACTION =
            "android.settings.APPLICATION_DETAILS_SETTINGS";
    private void openSetting() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.BASE) {
            Intent intent = new Intent()
                    .setAction(SETTINGS_ACTION)
                    .setData(Uri.fromParts("package",
                            getApplicationContext().getPackageName(), null));
            startActivity(intent);

        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Intent intent = new Intent()
                    .setAction(SETTINGS_ACTION)
                    .setData(Uri.fromParts("package",
                            getApplicationContext().getPackageName(), null));
            startActivity(intent);

        }
    }

2、跳转到设置

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.BASE) {
    // 进入设置系统应用权限界面
    Intent intent = new Intent(Settings.ACTION_SETTINGS);
    startActivity(intent);
    return;
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {// 运行系统在5.x环境使用
    // 进入设置系统应用权限界面
    Intent intent = new Intent(Settings.ACTION_SETTINGS);
    startActivity(intent);
    return;
}
