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
我有一个很棒的解决方案来实现这个，像这样创建一个BaseActivity。
public class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this));
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
switch (requestCode) {
case 1: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
CustomToast.getInstance().setCustomToast("Now you can share the Hack.");
} else {
Toast.makeText(this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
}
}
}
}
}
现在你可以像这样调用代码来请求许可
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
每次这发生在任何地方无论是在片段中还是在任何活动中基活动都会被调用。
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();
}
}
}
在你根据上面的答案检查一切之前，确保你的请求代码不是0!!
检查FragmentActivity.java中onRequestPermissionsResult()的代码:
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
int index = (requestCode>>16)&0xffff;
if (index != 0) {
index--;
String who = mPendingFragmentActivityResults.get(index);
mPendingFragmentActivityResults.remove(index);
if (who == null) {
Log.w(TAG, "Activity result delivered for unknown Fragment.");
return;
}
Fragment frag = mFragments.findFragmentByWho(who);
if (frag == null) {
Log.w(TAG, "Activity result no fragment exists for who: " + who);
} else {
frag.onRequestPermissionsResult(requestCode&0xffff, permissions, grantResults);
}
}
}
