Android 6.0 多重权限
此示例显示如何在 Android 6 及更高版本中检查运行时的权限。
public static final int MULTIPLE_PERMISSIONS = 10; // code you want.
String[] permissions = new String[] {
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION
};
@Override
void onStart() {
if (checkPermissions()){
// permissions granted.
} else {
// show dialog informing them that we lack certain permissions
}
}
private boolean checkPermissions() {
int result;
List<String> listPermissionsNeeded = new ArrayList<>();
for (String p:permissions) {
result = ContextCompat.checkSelfPermission(getActivity(),p);
if (result != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(p);
}
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case MULTIPLE_PERMISSIONS:{
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
// permissions granted.
} else {
// no permissions granted.
}
return;
}
}
}
