addView FILL_PARENT不工作 [英] addView FILL_PARENT not working
问题描述
我想提出一个布局到通过layoutInflater另一个。
I want to put a layout into another one via layoutInflater.
这里的main_layout.xml文件:
Here's the main_layout.xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="@+id/ads_image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/ic_launcher" />
<RelativeLayout
android:id="@+id/host_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/navigation_buttons_layout"
android:layout_alignParentLeft="true"
android:layout_below="@+id/ads_image_view" >
</RelativeLayout>
<RelativeLayout
android:id="@+id/navigation_buttons_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Button" />
</RelativeLayout>
和这里的vitrin_layout.xml文件:
and here's the vitrin_layout.xml file:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff0000"
android:text="smallred" />
终于为我的主要活动onCreate方法:
and finally the onCreate method for my main activity:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
ViewGroup parent = (ViewGroup) findViewById(R.id.host_layout);
View view = LayoutInflater.from(getBaseContext()).inflate(
R.layout.vitrin_layout, null);
parent.addView(view, LayoutParams.FILL_PARENT);
setTitle(getString(R.string.title_activity_vitrin));
}
的问题是,在vitrin_layout,不适合于它的父(host_layout);虽然我已经设置FILL_PARENT永远在那里我能!
我想不通为什么。
The problem is that the vitrin_layout, does not fit into its parent(host_layout); although I've set fill_parent where ever I could!
I can't figure out why.
编辑:我真的很抱歉,但我错了粘贴文件vitrin_layout,我固定它
Edited: I'm really sorry, but i'd pasted wrong vitrin_layout file, I fixed it.
推荐答案
使用此<一个href=\"http://developer.android.com/reference/android/view/ViewGroup.html#addView%28android.view.View,%20android.view.ViewGroup.LayoutParams%29\">addView方法。顺便说一句不使用 getBaseContext()
,除非你知道你为什么使用它,而是使用一个活动的背景下(这个
)。
Use this addView method. By the way don't use getBaseContext()
unless you know why you are using it, instead use context of an activity (this
).
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
ViewGroup parent = (ViewGroup) findViewById(R.id.host_layout);
View view = LayoutInflater.from(this).inflate(R.layout.vitrin_layout, null);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
parent.addView(view, params);
setTitle(getString(R.string.title_activity_vitrin));
}
