我正在更新我们的应用程序，以使用新的M运行时权限系统。
除了onRequestPermissionsResult()之外，它都在工作。我需要检查按下按钮的权限，如果成功，就发送一条短信。当我授权这样做时，对话框会关闭，但直到我再次按下按钮，它才会触发“发送文本”。
我已经在onRequestPermissionsResult()方法中调试和设置了断点，但它从未进入它。
首先调用这个方法:
private void askForPermission() {
String[] permissions = new String[]{Manifest.permission.SEND_SMS};
ActivityCompat.requestPermissions(getActivity(), permissions, PERMISSIONS_CODE);
}
然后我的回调函数是这样的:
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSIONS_CODE) {
for (int i = 0; i < permissions.length; i++) {
String permission = permissions[i];
int grantResult = grantResults[i];
if (permission.equals(Manifest.permission.SEND_SMS)) {
if (grantResult == PackageManager.PERMISSION_GRANTED) {
onPPSButtonPress();
} else {
requestPermissions(new String[]{Manifest.permission.SEND_SMS}, PERMISSIONS_CODE);
}
}
}
}
}
有人遇到过类似的问题吗?
感谢任何帮助。
谢谢
我有一个类似的问题，除了我按下一个按钮进行调用，这触发了callIntent。我首先检查权限，如果没有授予我要求权限和onRequestPermissionResult我调用检查权限，并再次调用。
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case Constants.PERMISSIONS_REQUEST_CALL_PHONE: {
if ( grantResults[0] == PackageManager.PERMISSION_GRANTED) {
checkPermissionsAndCall();
}
}
}
}
public void checkPermissionsAndCall(){
if (Build.VERSION.SDK_INT > 22) {
if(ContextCompat.checkSelfPermission(getContext(),
Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED){
requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, Constants.PERMISSIONS_REQUEST_CALL_PHONE);
}
else{
callIntent();
}
}
}
对于kotlin用户，这里我的扩展检查和验证权限没有覆盖onRequestPermissionResult
* @param permissionToValidate (request and check currently permission)
*
* @return recursive boolean validation callback (no need OnRequestPermissionResult)
*
* */
internal fun Activity.validatePermission(
permissionToValidate: String,
recursiveCall: (() -> Boolean) = { false }
): Boolean {
val permission = ContextCompat.checkSelfPermission(
this,
permissionToValidate
)
if (permission != PackageManager.PERMISSION_GRANTED) {
if (recursiveCall()) {
return false
}
ActivityCompat.requestPermissions(
this,
arrayOf(permissionToValidate),
110
)
return this.validatePermission(permissionToValidate) { true }
}
return true
}
在这里，我想展示我的代码我是如何做到这一点的。
public class CheckPermission {
public Context context;
public static final int PERMISSION_REQUEST_CODE = 200;
public CheckPermission(Context context){
this.context = context;
}
public boolean isPermissionGranted(){
int read_contact = ContextCompat.checkSelfPermission(context.getApplicationContext() , READ_CONTACTS);
int phone = ContextCompat.checkSelfPermission(context.getApplicationContext() , CALL_PHONE);
return read_contact == PackageManager.PERMISSION_GRANTED && phone == PackageManager.PERMISSION_GRANTED;
}
}
在这个类中，我想检查许可是否被授予。那我是不是会从我的MainActivity调用许可呢
public void requestForPermission() {
ActivityCompat.requestPermissions(MainActivity.this, new String[] {READ_CONTACTS, CALL_PHONE}, PERMISSION_REQUEST_CODE);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (shouldShowRequestPermissionRationale(ACCESS_FINE_LOCATION)) {
showMessageOKCancel("You need to allow access to both the permissions",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.CALL_PHONE},
PERMISSION_REQUEST_CODE);
}
}
});
return;
}
}
}
}
现在在onCreate方法中，你需要调用requestForPermission()函数。
就是这样。您也可以同时请求多个权限。
