我在Android应用中使用Google PlacePicker。我可以用它来选择地址。但是,一旦选择了地址,它就不会返回到呼叫者活动。相反,我必须按下“后退”按钮!
这是我初始化PlacePicker的方式:
/**
* Add New Address
*/
mNewButton.setOnTouchListener(new View.OnTouchListener()
{
@Override
public boolean onTouch(View view, MotionEvent motionEvent)
{
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
try
{
startActivityForResult(builder.build(AddressPickerActivity.this), ADDRESS_CODE);
}
catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e)
{
int status = GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(AddressPickerActivity.this);
GoogleApiAvailability.getInstance().getErrorDialog(AddressPickerActivity.this, status, 100).show();
}
return false;
}
});
这就是我收听结果的方式:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == ADDRESS_CODE)
{
if (resultCode == RESULT_OK)
{
Log.d(TAG, "Google PlacePicker finished");
// Do Stuff then finish current activity too
AddressPickerActivity.this.setResult(RESULT_OK);
AddressPickerActivity.this.finish();
}
}
}
问题是:除非按下位置选择器上的“后退”按钮,否则我不会收到日志消息“ Google PlacePicker finished
”!之后,一切正常进行,我要执行的操作正常(这意味着地址已正确选择)
存在类似的问题here,注释表明呼叫者活动清单中可能有android:noHistory="true"
。但是我检查了,事实并非如此。这是清单中的相应片段:
<activity
android:name=".AddressPickerActivity"
android:theme="@style/AppThemeNoActionBar" />
是什么原因造成的?
我还尝试了将android:noHistory="false"
显式添加到清单中。没有变化。

您可以使用OnClickListener
或尝试为startActivityForResult添加条件MotionEvent.ACTION_UP
,因为碰巧PlacePicker两次打开。
mNewButton.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if(motionEvent.getAction() == MotionEvent.ACTION_UP){
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
try {
startActivityForResult(builder.build(AddressPickerActivity.this), ADDRESS_CODE);
} catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
int status = GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(AddressPickerActivity.this);
GoogleApiAvailability.getInstance().getErrorDialog(AddressPickerActivity.this, status, 100).show();
}
}
return false;
}
});
