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
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
}
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
