我对 onActivityResult 有疑问,无论我在做什么,我都无法获得正确的 resultCode。
我知道有类似的问题,但最后他们没有帮助我,我无法解决
MainActivity: 将打开新 Activity Popup.class
的方法public void openShopView(){
Intent intent = new Intent(this, Popup.class);
Bundle b = new Bundle();
b.putString("which", "ShopMain");
intent.putExtras(b);
startActivityForResult(intent, 1);
}
第二个 Activity: 将打开另一个 Activity Popup.class 的方法,只是布局不同
shop_c1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getIntent());
Bundle b = new Bundle();
b.putString("which", "ShopBuildings");
intent.putExtras(b);
startActivity(intent);
finish();
}
});
第三个 Activity: 还有一个方法应该设置结果并关闭 Activity
building2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.i("LOG_NEW: ", "" + getCurrentBuildingTable(1) + ", " + checkSlotTable(1));
if(getCurrentBuildingTable(1) && checkSlotTable(1) == -1) {
Intent returnIntent = getIntent();
returnIntent.putExtra("result", 1);
setResult(RESULT_OK, returnIntent);
finish();
}else if (checkSlotTable(1) == -1){
Log.i("LOG_NEW: ", "Building already exist");
}
else{
Log.i("LOG_NEW: ", "Not enough resources");
}
}
});
最后是来自 MainActivity 的 onActivityResult()
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.i("LOG_RES: ", "Checking.. " + requestCode + ", " + resultCode);
if (requestCode == 1) {
if(resultCode == RESULT_OK){
String result = data.getStringExtra("result");
Log.i("LOG_RES: ", result);
}
}
}
无论我在做什么,我都无法启动 if(resultCode == RESULT_OK) 循环并且 resultCode 始终为 0..
感谢帮助
最佳答案
setResult
必须在 Second Activity 中调用,因为第二个 Activity 的 Intent 已在 startActivityForResult
中传递。
但是,您可以将第三个 Activity 的结果代码委托(delegate)给第二个 Activity ,然后再委托(delegate)给第三个。
将您的第二个 Activity 更改为如下内容:
shop_c1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getIntent());
Bundle b = new Bundle();
b.putString("which", "ShopBuildings");
intent.putExtras(b);
startActivityForResult(intent,1);
//Remove finish from here
}
});
然后在 Second Activity 中也添加这个
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==1){
setResult(resultCode,data);
}
finish();
}
关于android - onActivityResult - resultCode 始终为 0,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42032387/
