android-片段超出屏幕
作者：互联网
我刚刚将片段添加到Main_Activity中,现在将它们与抽屉布局交换,
这里的问题是该片段未包含在屏幕内部,如图所示,
如果有人需要,我会提供代码.
简要地说,我添加了一个线性布局,其中片段被交换了
<LinearLayout
android:orientation="vertical"
android:id="@+id/container"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</LinearLayout>
这是请求的代码：
HEER“ activity_main.xml”
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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:clipToPadding="false"
android:fitsSystemWindows="true">
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/DrawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

<include

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World" />
<LinearLayout

android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/RecyclerView"
android:layout_width="320dp"

android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>

这里是片段类别之一：
package com.rateker.ratekerand.ratekerandroid;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
/**
* A simple {@link android.app.Fragment} subclass.
*/
public class FragmentHome extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragmenthome, container, false);
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
这是片段的XML：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:orientation="vertical">
<TextView
android:padding="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text=" HOME 1 HOME 2 HOME 3 HOME 4 HOME 5 HOME 6 HOME 7 HOME 8 HOME 9 HOME 11 HOME 12 HOME 13 HOME 14 HOME 15 HOME 16 HOME 17 HOME 18 HOME 19"
android:id="@+id/textView"
android:layout_gravity="center_horizontal" />
</LinearLayout>
解决方法:
事实证明,我在模拟器的宽度和高度方面存在问题.窗口高度应与客人高度相同,宽度应相同.
