馬里奧我想知道你打算使用App的權限創建首選項,但是在這裏你得到了一個解決方案。
try {
PackageInfo packageInfo = getPackageManager().getPackageInfo(myPackageName, PackageManager.GET_PERMISSIONS);
String[] requestedPermissions = packageInfo.requestedPermissions;
if (requestedPermissions != null) {
for (int i = 0; i < requestedPermissions.length; i++) {
//permission.setSummary(requestedPermissions[i] + "\n");
//method to create a preference with the name of your permission.
setPreference(this, requestedPermissions[i]);
}
}
}
catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
創建偏好的方法。
public static void setPreference(Context context, String preferenceName)
{
SharedPreferences settings = context.getSharedPreferences(preferenceName, 0);
SharedPreferences.Editor editor = settings.edit();
//Add a key to this preference and his value.
editor.putString(preferenceName+"_value", "Value stored in preference called: " + preferenceName);
editor.commit();
}
創建讀取存儲在您的喜好值的方法
public static String getPreference(Context context, String preferenceName){
SharedPreferences settings = context.getSharedPreferences(preferenceName, 0);
return settings.getString(preferenceName+"_value", "");
}
,那麼你可以讀取存儲在你的喜好值,例如,讀取存儲在優先值稱爲
「android.permission.INTERNET」
:
個在吐司
Log.i("Preferences", getPreference(this,"android.permission.INTERNET"));
例如Displayin數據:
Toast.makeText(this, "the value stored in \"android.permission.INTERNET\" preference is: " + getPreference(this,"android.permission.INTERNET"), Toast.LENGTH_LONG).show();
添加每個權限的偏好?你究竟是什麼意思?您想做什麼 ? – gahfy
例如,如果應用程序需要三個許可證,我想每個許可證都有三個首選項。 –
