Question

我有一个dialogFragment，它的组件布局和一个管理其动作的类。一切都很好。我想在对话框中选择布局组件时返回一个值 - 我该怎么做？

该对话框由一组布局组成，这些布局附有一个动作侦听器。我不知道在哪里放这个 - 但是不能让对话框对任何按下布局做出反应。

我的xml

    <LinearLayout xmlns:android='http://schemas.android.com/apk/res/android'
        android:id='@+id/background'
        android:layout_width='fill_parent'
        android:layout_height='fill_parent'
        android:orientation='vertical'
        android:padding='10sp'
        android:background="@color/green"
        android:baselineAligned="false">

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="50dp">

            <LinearLayout
                android:orientation="vertical"
                android:layout_width="50dp"
                android:layout_height="50dp"
                android:layout_weight="1"
                android:id="@+id/linearLayout_colorR1C1"
                android:clickable="true"
                android:background="#548235">

            </LinearLayout>

            <LinearLayout
                android:orientation="vertical"
                android:layout_width="50dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:id="@+id/linearLayout_colorR1C2"
                android:background="#f100b050">

            </LinearLayout>
   </LinearLayout>
</LinearLayout>

        //do something after you get the value
        ll_primaryColor.setBackgroundColor(Color.parseColor(inputText));
    }
    }

Answer 1

知道了，我删除了onEditorAction并使用listenr更新了onCreate。完美。

LinearLayout myLinearLayout = (LinearLayout) cardView.findViewById(R.id.my_linear_layout);
myLinearLayout.removeAllViews();

DialogFrament没有认出我的行动
