布尔本身重置为false时getExtra被称为 [英] Boolean resets itself to false when getExtra is called
问题描述
当我调用getExtras.getBoolean(键)请将isDeleted我布尔值,它会保持自身设置为false,即使我传入true。为什么这任何有识之士正在发生?我已经尝试了很多其他的方法,但都没有成功,在保持布尔值true。
其他活动:
公共无效deleteWorkout(查看视图)
{
intent.putExtra(listPosition,intent.getExtras()调用getInt(位置));
intent.putExtra(请将isDeleted,真正的);
的setResult(RESULT_OK,意图);
完();
}
主要活动:
情况(列表):{
如果(RES code == Activity.RESULT_OK)
{
请将isDeleted布尔= intent.getExtras()getBoolean(请将isDeleted)。
INT listPosition = intent.getExtras()调用getInt(listPosition)。
如果(请将isDeleted)
{
adapter.remove(workoutList.get(listPosition));
adapter.notifyDataSetChanged();
}
}
}
默认:
打破;
}
有双向通/获取数据的一个活动到另一个活动。
1.新增数据的意图。
如何把:
intent.putExtra(listPosition,intent.getExtras()调用getInt(位置));
intent.putExtra(请将isDeleted,真正的);
如何获得:
INT listPosition = getIntent()getIntExtra(listPosition,0);
请将isDeleted布尔= getIntent()getBooleanExtra(请将isDeleted,假)。
2.添加数据捆绑,并添加束意图。
如何把:
捆绑包=新包();
bundle.putExtra(listPosition,intent.getExtras()调用getInt(位置));
bundle.putExtra(请将isDeleted,真正的);
intent.putExtras(束)
如何获得:
INT listPosition = getIntent()getExtras()调用getInt(listPosition,0)。;
请将isDeleted布尔= getIntent()getExtras()getBoolean(请将isDeleted,FALSE)。;
When I invoke getExtras.getBoolean(key) for my isDeleted boolean, it keeps setting itself to false, even though I'm passing in true. Any insight on why this is occurring? I've tried a lot of other methods, but haven't been successful in keeping the boolean value TRUE.
Other Activity:
public void deleteWorkout(View view)
{
intent.putExtra("listPosition", intent.getExtras().getInt("position"));
intent.putExtra("isDeleted", true);
setResult(RESULT_OK, intent);
finish();
}
Main Activity:
case(List): {
if(resCode == Activity.RESULT_OK)
{
boolean isDeleted = intent.getExtras().getBoolean("isDeleted");
int listPosition = intent.getExtras().getInt("listPosition");
if(isDeleted)
{
adapter.remove(workoutList.get(listPosition));
adapter.notifyDataSetChanged();
}
}
}
default:
break;
}
There is two way pass/get data one activity to another activity.
1.add data to intent.
how to put :
intent.putExtra("listPosition", intent.getExtras().getInt("position"));
intent.putExtra("isDeleted", true);
how to get :
int listPosition = getIntent().getIntExtra("listPosition",0);
boolean isDeleted = getIntent().getBooleanExtra("isDeleted",false);
2.Add data to bundle and add bundle to intent.
how to put :
Bundle bundle = new Bundle();
bundle.putExtra("listPosition", intent.getExtras().getInt("position"));
bundle.putExtra("isDeleted", true);
intent.putExtras(bundle)
how to get :
int listPosition = getIntent().getExtras().getInt("listPosition",0);
boolean isDeleted = getIntent().getExtras().getBoolean("isDeleted",false);
