我的要求是我需要显示一些需要在底部显示的事件的信息。我创建了一个布局,当事件发生时,我正在使用下面的方法:
XML布局
<RelativeLayout android:id="@+id/maincontainer"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:paddingLeft="@dimen/activity_horizontal_margin"
tools:context=".HomeActivity"
>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="BB"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="AA"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:weightSum="1">
<Button
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="5dp"
android:layout_weight="0.5"
android:text="PP"/>
<Button
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginLeft="5dp"
android:layout_weight="0.5"
android:text="GG"/>
</LinearLayout>
</RelativeLayout>
显示底部视图的代码:
// To check main container where new view is to be added
android.view.ViewGroup insertPoint = (android.view.ViewGroup) findViewById(R.id.maincontainer);
// New View that needs to be added
android.view.LayoutInflater vi = (android.view.LayoutInflater) getApplicationContext().getSystemService(android.content.Context.LAYOUT_INFLATER_SERVICE);
android.view.View v = vi.inflate(R.layout.app_flow_error, null);
android.widget.TextView textView = (android.widget.TextView) v.findViewById(cR.id.information_message);
textView.setText("Showing error");
//Defining the params value for new view that needs to be added
android.widget.RelativeLayout.LayoutParams layoutParams = new android.widget.RelativeLayout.LayoutParams(android.view.ViewGroup.LayoutParams.MATCH_PARENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
layoutParams.addRule(android.widget.RelativeLayout.ALIGN_PARENT_BOTTOM);
insertPoint.addView(v, insertPoint.getChildCount()-1, layoutParams);
v.setHovered(true);
需要在底部显示的视图,完全采用底部屏幕,但按钮&#34; BB&#34;出现 。
你能让我知道我在做什么错,所以按钮&#34; BB&#34;在底部添加新视图时应该隐藏吗?
答案 0 :(得分:1)
出于测试目的,请尝试使用(Relative, Linear etc.)Layout
而不是BB Button
,看看它是否适用于这种情况(我的意思是看红色布局是否位于其他布局的顶部) 。我怀疑这是因为Button
指定了一个高程(默认情况下,不是你),而且它是#34;被提升的#34;在你正在展示的东西之上(我猜你在Lollipop上运行+)。如果是这种情况,您可以将红色布局的高程设置为大于Button
的高程,或者使用已经具有该高程布局的布局(CardView
?)

//test purpose
android.view.ViewGroup insertPoint = (android.view.ViewGroup) view.findViewById(R.id.maincontainer);
// New View that needs to be added
android.view.LayoutInflater vi = (android.view.LayoutInflater)
getApplicationContext().getSystemService(android.content.Context.LAYOUT_INFLATER_SERVICE);
android.view.View v = vi.inflate(R.layout.app_flow_error, insertPoint, false);
android.widget.TextView textView = (android.widget.TextView) v.findViewById(cR.id.information_message);
textView.setText("Showing error");
//Defining the params value for new view that needs to be added
android.widget.RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) v.getLayoutParams();
layoutParams.addRule(android.widget.RelativeLayout.ALIGN_PARENT_BOTTOM);
v.setLayoutParams(layoutParams);
insertPoint.addView(v, layoutParams);
v.setHovered(true);
P.S。请在检查后标记为答案。
