我有一个活动,可以为结果启动子活动。启动子活动时,在其finish()
方法中,我将一些数据添加到包bunConnAssets
然后将此捆绑包添加到意图intConnAssets
,最后调用setResult(RESULT_OK, intConnAssets);
问题是,在运行时,当我关闭子活动,因此调用其finish()
方法时,mainActivity中的onActivityResult
被调用,但其中的switch-case
被调用不叫。但是
else {
Log.d(TAG, "resultCode != RESULT_OK");
}
被调用,这意味着从subActivity返回的resutCode不正常
为什么会这样?
子活动:
@Override
public void finish() {
// TODO Auto-generated method stub
super.finish();
Log.w(TAG, "@finish().");
if (this.mqttSettingsDB != null) {
Log.d(TAG, "this.mqttSettingsDB is not null.");
int[] id = this.mqttSettingsDB.getIDs();
Bundle bunConnAssets = new Bundle();
Intent intConnAssets = new Intent();
....
....
....
intConnAssets.putExtras(bunConnAssets);
setResult(RESULT_OK, intConnAssets);
} else {
Log.wtf(TAG, "this.mqttSettingsDB is null.");
}
}
onActivityResult :
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Log.d(TAG, "onActivityResult");
switch (requestCode) {
case REQUEST_CODE:
if (resultCode == RESULT_OK) {
if (data != null) {
if (data.hasExtra("bunConnAssets")) {
Log.d(TAG, "Bundle exists");
} else {
Log.d(TAG, "Bundle does not exist");
}
}
} else {
Log.d(TAG, "resultCode != RESULT_OK");
}
break;
default:
Log.e(TAG, "Unexpected RequestCode.");
break;
}
}

您在第一行调用super.finish()
,因此可能无法执行其余代码。
在代码末尾调用super方法。

尝试使用以下代码
@Override
public void finish() {
Log.w(TAG, "@finish().");
if (this.mqttSettingsDB != null) {
Log.d(TAG, "this.mqttSettingsDB is not null.");
int[] id = this.mqttSettingsDB.getIDs();
Bundle bunConnAssets = new Bundle();
Intent intConnAssets = new Intent();
....
....
....
intConnAssets.putExtras(bunConnAssets);
setResult(RESULT_OK, intConnAssets);
} else {
Log.wtf(TAG, "this.mqttSettingsDB is null.");
}
super.finish();
}
