我如何才能在布局的底部放置一個Button，並使其即使在鍵盤打開時也可以停留在該位置？

Question

嗨，以下是我的布局

<?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="#aaaaaa"
    android:id="@+id/mainLayout"       
    android:orientation="vertical" >
<LinearLayout
    android:layout_width="match_parent"
    android:orientation="horizontal"
    android:layout_marginTop="55dp"
    android:layout_height="wrap_content"
    android:gravity="top">
  <include layout="@layout/search_bar"/> 

  </LinearLayout>
<android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="fill_parent" />
<LinearLayout
    android:layout_width="match_parent"
    android:layout_gravity="bottom"
    android:orientation="horizontal"
    android:layout_height="50dp"
    android:background="#eeeeee"
    android:gravity="bottom">
    <ImageButton
        android:id="@+id/ImageButton1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal|bottom"
        android:layout_marginLeft="1dip"
        android:layout_marginRight="1dip"
        android:src="@drawable/appdrawer" />
    </LinearLayout>
    </LinearLayout>

打開布局時，ImageButton顯示在底部，但是當我將焦點放在SearchBox上時，鍵盤將打開，並且將ImageButton向上推。 如何使ImageButton保持頁腳。

Answer 1

您應該使用相對布局而不是線性布局，並添加android: layout_alignParentBottom="true" 。

從活動清單中添加set stateHidden|adjustpan android:windowSoftInputMode 。

Answer 2

這是布局...

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white">

    <include
        android:id="@+id/activity_appointment_header"

    // Your header If any
    </include>

    <ScrollView
        android:id="@+id/scroll_view"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@id/activity_appointment_header"
        android:layout_marginBottom="65dp"
        android:background="@color/white"
        android:fillViewport="true"
        android:scrollbars="none" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

           // Keep your layout

        </LinearLayout>
    </ScrollView>



    <LinearLayout
        android:id="@+id/ll_book_appointment_btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/scroll_view"
        android:layout_alignParentBottom="true"
        android:gravity="center_horizontal"
        android:orientation="vertical" >

        <View
            android:layout_width="match_parent"
            android:layout_height="1dip"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:background="@color/cp_red" />

        <Button
            android:id="@+id/btn_book_appointment"
            style="@style/buttonStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="5dp"
            android:layout_marginTop="5dp"
            android:text="@string/book_now" />
    </LinearLayout>

</RelativeLayout>

並且您的活動應該在manifest.xml是這樣的

 <activity
         android:name=".Activity"

         android:windowSoftInputMode="stateAlwaysHidden|adjustResize" >
   </activity>

Answer 3

嘗試將其添加到manifest.xml

        <activity
            android:name=".YourActivity"
            android:configChanges="keyboardHidden|keyboard"
            android:windowSoftInputMode="stateHidden|adjustNothing" >
        </activity>

Answer 4

使用android：windowSoftInputMode =“ adjustPan”來顯示在相應的活動中：

  <activity android:name="MyActivity"
    ...
    android:windowSoftInputMode="adjustPan"
    ...
  </activity>

用下面替換

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#aaaaaa"
    android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="55dp"
    android:gravity="top"
    android:orientation="horizontal" >

    <include layout="@layout/search_bar" />
</LinearLayout>

<android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_gravity="bottom"
    android:background="#eeeeee"
    android:gravity="bottom"
    android:orientation="horizontal" >

    <ImageButton
        android:id="@+id/ImageButton1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal|bottom"
        android:layout_marginLeft="1dip"
        android:layout_marginRight="1dip"
        android:src="@drawable/appdrawer" />
</LinearLayout>

</LinearLayout>
