我的xml代码中有这个布局:

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

    <ImageView
        android:id="@+id/MainBg"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scaleType="centerCrop" />

    <RelativeLayout
        android:id="@+id/InboxTitleLyout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/PlayerImage"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scaleType="centerCrop"
            android:src="@drawable/silhouette_small" />

        <TextView
            android:id="@+id/Title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20dip"
            android:layout_marginLeft="10dip"
            android:layout_marginTop="3dip"
            android:textColor="@android:color/black"
            android:layout_toRightOf="@+id/PlayerImage"
            android:layout_alignTop="@+id/PlayerImage" />

        <Button
            android:id="@+id/BuddyBtn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/invite_friends_btn"
            android:lines="1"
            android:textColor="#ffffff"
            android:gravity="center" />

    </RelativeLayout>

    <LinearLayout
        android:id="@+id/NewMessagelayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:gravity="center"
        android:focusable="true"
        android:focusableInTouchMode="true">

        <EditText
            android:id="@+id/EditText"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:maxLength="140" />

        <Button
            android:id="@+id/ReplyBtn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

    </LinearLayout>

    <ListView
        android:id="@+id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:fadingEdge="none"
        android:cacheColorHint="#00000000"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:scrollbarStyle="outsideInset"
        android:layout_below="@id/InboxTitleLyout"
        android:layout_above="@id/NewMessagelayout"
        android:scrollbarSize="5dip"
        android:smoothScrollbar="true"
        android:listSelector="#00000000"
        android:background="@android:color/white" />

    <LinearLayout
        android:id="@+id/android:empty"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_centerInParent="true"
        android:layout_below="@id/InboxTitleLyout"
        android:background="@android:color/white"
        android:gravity="center">

        <TextView
            android:id="@+id/EmptyListMsg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#000000" />

        <TextView
            android:id="@+id/EmptyListBtn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:textColor="#000000" />

    </LinearLayout>

</RelativeLayout>

以下是我正在设置布局的代码:

int editHeight = (int)(screenHeight * 0.12f);
        editHeight = (editHeight < 20) ? editHeight = 20 : editHeight;
    LinearLayout.LayoutParams editParams = new LinearLayout.LayoutParams((int)(editTextBoxPercentage * screenWidth),editHeight);
replyET.setLayoutParams(editParams);

LinearLayout.LayoutParams replyParams = new LinearLayout.LayoutParams((int)(replyBtnPercentage * screenWidth),editHeight);
sendReply.setLayoutParams(replyParams);

当我开始这个活动时,我没有看到NewMessageLayout Linearlayout,但是当我按下它的位置时,键盘弹出,我可以输入文本 - 它接收事件。 我不明白为什么布局没有绘制。

感谢。
