我在Activity中的Fragment中有一个EditText.

我的活动布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@drawable/login_bg">
    ...

    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    ...

</RelativeLayout>

AndroidManifest.xml中的我的Activity配置:

    <activity
        android:name="com.demo.LoginActivity"
        android:configChanges="orientation|keyboardHidden"
        android:launchMode="singleTop"
        android:screenOrientation="portrait"
        android:theme="@style/activityTheme" />

用于在Activity中启动片段的代码:

private void startFragment(BaseFragment fragment, String tag) {
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(R.id.fragment_container, fragment);
    fragmentTransaction.addToBackStack(tag);
    fragmentTransaction.commitAllowingStateLoss();
}

我的片段布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/common_background_color_white"
    android:orientation="vertical"
    android:clickable="true"
    android:paddingLeft="@dimen/email_common_padding_horizontal"
    android:paddingRight="@dimen/email_common_padding_horizontal">

    ...

    <com.example.widget.LineEditView
        android:id="@+id/login_email_input"
        style="@style/BaseEditText.LoginEditText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
    />

    ...

</LinearLayout>

我的自定义窗口小部件LineEditView是子类扩展RelativeLayout,它的布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/input" …
