[問題]startActivityForResult搭配onBackPressed
A.class
onCreate:
{
Intent intent = new Intent("test1");//會跳到B.class
Bundle bundle = new Bundle();
bundle.putString("toB", "toB");
intent.putExtras(bundle);
startActivityForResult(intent, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent
data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
String returnValue = data.getExtras().getString("toA");
Log.e("onActivitiyResult", returnValue);
}
break;
default:
}
}
-----------------------------------------------------------------------------
B.class
public void onBackPressed() {
super.onBackPressed();
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
Log.e("Act2", ""+bundle.getString("toB"));
bundle.putString("toA","toA");
intent.putExtras(bundle);
setResult(RESULT_OK, intent);
finish();
}
我如果把這個fun寫在B.class的onCreate，A.class的onActivityResult就找得到
但寫在onBackPressed()就無法
但我希望使用者從A跳到B時，若按了Back鍵可以回傳值，應該要寫在這沒錯吧?
請問是哪個地方出問題了呢?
