【问题描述】:
在这里,我尝试将一些值传递给第二个活动(孩子)到第一个活动(父母)。我注意到在 API-21 中调用了设备 onActivityResult 的以上版本,但对于 API-19 及以下版本,它没有被调用。这里分享我的sn-ps代码,请查收。
感谢您的回答!!!
在父活动中:
第 1 步
Intent intent = new Intent(ABCAct.this, DEF.class);
intent.putExtra("mapPickDrop", "1");
intent.putExtra("location_lat", P_latitude);
intent.putExtra("location_lng", P_longitude);
intent.putExtra("address", pickupAddressFlag);
startActivityForResult(intent, 2018);
第 2 步:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 2018) {
if (resultCode == RESULT_OK) {
Double lat = data.getDoubleExtra("location_lat", 0.0);
Double lng = data.getDoubleExtra("location_lng", 0.0);
String add = data.getStringExtra("location_address");
String mapPickDrop = data.getStringExtra("mapPickDrop");
if (mapPickDrop.equals("1")) {
P_latitude = lat;
P_longitude = lng;
pickupAddressFlag = add;
TaxiUtil.bookTaxiPickUpDrop = 1;
if (P_latitude != 0.0 && P_longitude != 0.0 && D_latitude == 0.0 && D_longitude == 0.0) {
setLocation(P_latitude, P_longitude, "");
}
}
if (mapPickDrop.equals("2")) {
TaxiUtil.bookTaxiPickUpDrop = 2;
D_latitude = lat;
D_longitude = lng;
DroplocEdt.setText("" + add);
showPickupDropMarkers();
}
}
}
}
在子活动中
Intent back = new Intent();
back.putExtra("location_lat", P_latitude_new);
back.putExtra("location_lng", P_longitude_new);
back.putExtra("location_address", PicklocEdt_1.getText().toString());
back.putExtra("mapPickDrop", mapPickDrop);
setResult(RESULT_OK, back);
finish();
清单

您的清单看起来如何?

请检查清单代码@MuratK。

移除 android:launchMode="singleTask".
