对于想了解android-基于主题的LinearLayout背景的读者，本文将提供新的信息，我们将详细介绍linearlayout设置背景，并且为您提供关于Android LayoutInflater初始化RelativeLayout和LinearLayout的问题。、android linearlayout、Android linearLayout 之 layout_weight 揭秘、Android linearLayout 之 layout_weight揭秘的有价值信息。

android-基于主题的LinearLayout背景（linearlayout设置背景）

我有一个可绘制的背景(称为card_background_selector_light),基本上是这样的：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/card_state_pressed_light" android:state_pressed="true" />
    <item android:drawable="@drawable/card_background_light" />
</selector>

我有一个几乎相同的可绘制对象,称为card_background_selector_dark.现在,根据主题,我想展示一个或另一个.

为此,我在attrs.xml中定义了一个属性：

<attr name="listItemBackground" format="reference"></attr>

并将其包括在我的两种样式中：

<style name="AppThemeDark" parent="android:Theme.Holo">
    <item name="listItemBackground">@drawable/card_background_selector_dark</item>
</style>

和

<style name="AppThemeLight" parent="android:Theme.Holo.Light">
    <item name="listItemBackground">@drawable/card_background_selector_light</item>
</style>

现在,实际的LinearLayout如下所示：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:background="?attr/listItemBackground">

</LinearLayout>

一切在Android Studio预览中都可以正常工作(我可以更改主题,并且它也会相应地更改),但是一旦我尝试在实际设备上运行它,就会遇到以下异常：

我在这里阅读了很多其他线程(例如this one和this one),它们基本上以相同的方式进行操作,但是不知怎么对我不起作用.有任何想法吗？

更新资料

根据要求,这是我的活动的onCreate()方法：

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
    setTheme(preferences.getBoolean(PreferenceUtils.PREF_THEME, isDefaultThemeDark()) ? DARK_THEME : LIGHT_THEME);

    setContentView(R.layout.activity_main);

    INSTANCE = this;

    /* Make sure the default preferences are set */
    PreferenceUtils.setDefaults(this);

    databaseHandler = new DatabaseHandler(this);

    List<Row> items = databaseHandler.getAllItems();
    adapter = new ListRowAdapter(getApplicationContext(), android.R.layout.simple_list_item_1, items);

    if (items.size() > 0)
    {
        Row row = items.get(items.size() - 1);
        int col = row.getLastFilledColumn() + 1;

        if (col == getNrOfBarcodes())
        {
            currentColumn = 0;
        }
        else
        {
            currentColumn = col;
            currentListRow = row;
        }
    }

    listView = (ListView) findViewById(R.id.list_scanned_items);
    listView.setAdapter(adapter);

    hiddenInput = (EditText) findViewById(R.id.input);
    hiddenInput.setonKeyListener(this);
    hiddenInput.requestFocus();

    /* Redirect every focus from the list view to the input text */
    listView.setonFocuschangelistener(this);

    setCodeFormats();
}

解决方法:

您正在使用应用程序上下文来增加列表项.尝试使用活动的上下文.

adapter = new ListRowAdapter(this, android.R.layout.simple_list_item_1, items);

Android LayoutInflater初始化RelativeLayout和LinearLayout的问题。

我自定义一个MyListView extends ListView, 在自定义的MyListView的构造函数里使用LayoutInflater初始化一个布局为RelativeLayout布局，然后获取这个RelativeLayout布局的宽和高时报错，使用LinearLayout就能够正常获取。

不知道这是什么情况。

MainActivity.java:

package com.fyfeng.listviewtest;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

	}

}

主配置文件activity_main.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFD700"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <com.fyfeng.listviewtest.MyListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
    </com.fyfeng.listviewtest.MyListView>

</RelativeLayout>

自定义的MyListView extends ListView

package com.fyfeng.listviewtest;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

public class MyListView extends ListView {
	
	private static final String tag = MyListView.class.getSimpleName();

	private int mHeaderWidth;
	private int mHeaderHeight;
	
	public MyListView(Context context) {
		super(context);
		this.init();
	}

	public MyListView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		this.init();
	}

	public MyListView(Context context, AttributeSet attrs) {
		super(context, attrs);
		this.init();
	}

	private void init() {
		LayoutInflater lif = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		View header = lif.inflate(R.layout.header, null);

		this.addHeaderView(header);
		
		measureView(header);
		mHeaderWidth = header.getMeasuredWidth();
		mHeaderHeight = header.getMeasuredHeight();
		Log.d(tag, "header width = " + mHeaderWidth + ", height = " + mHeaderHeight);
		
	}

	// 计算headView的width及height值
	private void measureView(View child) {

		ViewGroup.LayoutParams p = child.getLayoutParams();

		if (p == null) {
			p = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
		}

		int childWidthSpec = ViewGroup.getChildMeasureSpec(0, 0 + 0, p.width);
		int lpHeight = p.height;
		int childHeightSpec;

		if (lpHeight > 0) {
			childHeightSpec = MeasureSpec.makeMeasureSpec(lpHeight, MeasureSpec.EXACTLY);
		} else {
			childHeightSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
		}

		child.measure(childWidthSpec, childHeightSpec);
	}
}

private void measureView(View child) ;这个方法是直接从osc客户端源码里拷贝过来的。

ListView的headerView配置header.xml：

<?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" >
    
    <TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world"
        />

</RelativeLayout>

初始化完这个header布局后，调用measureView(View child)方法就会报空指针异常：

如果把header.xml中的RelativeLayout改为LinearLayout一切正常，能够获取宽和高。

谁遇到这种问题？有解的赐教一下。
