Question

我有像这样的线性布局

<LinearLayout
    android:id="@+id/optionlist"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/divider"
    android:orientation="vertical" >

</LinearLayout>

我想在此布局中添加另一个xml视图

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/option"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <!--
               <View 
               android:layout_width="match_parent"
               android:layout_height="0.5dip"
               android:layout_marginLeft="10dp"
                 android:layout_marginRight="10dp"
                android:background="#2fd275"
               />
    -->

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:padding="10dp" >

        <ImageView
            android:id="@+id/option_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:src="@drawable/logout" />

        <TextView
            android:id="@+id/option_id"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:textColor="#000000"
            android:visibility="gone" />

        <TextView
            android:id="@+id/option_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_margin="10dp"
            android:text="Signout"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="#616161" />
    </LinearLayout>

    <View
        android:id="@+id/divider"
        android:layout_width="match_parent"
        android:layout_height="0.5dip"
        android:background="#d3d3d3" />

</LinearLayout>

通过代码

    for (int i = 0; i < opt.length; i++) {

        View view = inflater.inflate(R.layout.option_item, optionlist,
                false);
        view.setBackgroundResource(R.drawable.optionlist);
        view.setTag(opt_image[i]);
        view.setClickable(true);
        view.setFocusable(true);

        view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // ADD your action here

                int res = (Integer) v.getTag();

                switch (res) {
                case R.drawable.logout:
                    signout();
                    break;
                }

            }
        });
        final TextView tv = (TextView) view.findViewById(R.id.option_name);
        final ImageView iv = (ImageView) view
                .findViewById(R.id.option_image);
        tv.setText(opt[i]);
        iv.setImageResource(opt_image[i]);
        optionlist.addView(view);
    }

现在点击布局我想加载这个xml文件，如下所示...但我无法在点击事件中加载背景。请提出建议我做错了什么？

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

    <item android:drawable="@color/holo_green_dark" android:state_focused="true"/>
    <item android:drawable="@color/holo_green_dark" android:state_enabled="false" android:state_pressed="true"/>
    <item android:drawable="@color/white"/>

</selector>

Answer 1

首先从xml获取LinearLayout的id，然后在其上执行onClickListener而不是整个View

View view  = inflater.inflate(R.layout.option_item, optionlist, false);
LinearLayout layout = view.findViewByIt(R.id.optionlist);
layout.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
      // ADD your action here
      int res=(Integer) v.getTag();
      switch(res)
      {
         case R.drawable.logout: signout();
                                break;
      }
   }
});

Answer 2

试试这个..希望它有效..

  <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" 
        android:drawable="#ff0000" />//ur onclick desired color 
    <item  android:state_focused="false" 
        android:drawable="@android:color/transparent" />focused color
   </selector>

只需创建新的xml并将此代码添加到drawable中并将其设置为线性layoyut backgrout，其名称为android:background="@drawable/createdxmlname"

<LinearLayout
        android:id="@+id/optionlist" 
        android:layout_below="@id/divider"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:background="@drawable/createdxmlname"
        android:clickable="true">

Answer 3

   android:clickable="false"


 <LinearLayout  
      android:id="@+id/parent"  
      android:layout_width="match_parent"  
      android:layout_height="wrap_content"  
      android:orientation="horizontal">  
      <ImageButton  
           android:clickable="false"  
           android:layout_width="40dp"  
           android:layout_height="40dp"  
           android:text="Cinema"  
           android:textSize="13sp"  
           android:layout_marginRight="10dp" />  
      <Button  
           android:clickable="false"  
           android:layout_width="match_parent"  
           android:layout_height="40dp"  
           android:text="Check in"  
           android:textSize="13sp" />  
 </LinearLayout>

Answer 4

在drawable中创建一个带有以下内容的pressed_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_pressed="true"
      android:drawable="@drawable/button_pressed" /> <!-- pressed -->
   <item android:state_focused="true"
      android:drawable="@drawable/button_focused" /> <!-- focused -->
   <item android:drawable="@drawable/button_normal" /> <!-- default -->
 </selector>

在您的布局中将其添加为背景资源：

<LinearLayout
  android:layout_height="wrap_content"
  android:layout_width="wrap_content"
  android:background="@drawable/pressed_layout"
  android:clickable="true">
</LinearLayout>

Answer 5

XML文件中的

layout.setclickble =“true”和

layout.setOnLongClickListener（new View.OnLongClickListener（）{

Get-Content 'c:\temp\ps\pc.txt' | ForEach-Object {
  ...
} | ConvertTo-Csv -NoType | Tee-Object -FilePath 'C:\temp\ps\output.txt'

Answer 6

我们也可以在布局的XML中使用onClick，并在java文件中使用该方法，如onClick =＆＃34; next＆＃34;，然后在java文件中我们必须使用该方法。

// get the rows that contain proxies
var proxies = htmlDoc.DocumentNode.SelectNodes("//tr[td/a[@title='Proxy details']]");

if (proxies != null)
{
    foreach (var proxy in proxies)
    {
        // process this proxy row
        Console.WriteLine("IP:" + proxy.SelectSingleNode(td/a[@title='Proxy details']).InnerText);
        Console.WriteLine("PORT:" + proxy.SelectSingleNode(td[2]).InnerText);
    }
}

Console.ReadLine();
