我很抱歉,如果之前已经发布过,或者可能没有,但我遇到了几个图像按钮的问题,当我按下它们时它不会改变图像。我使用了与我的标签一样的逻辑,我调用了x.xml(x是一个示例名称)文件,该文件存储在我的drawable文件夹中,并从相应的图像按钮调用该文件夹。
这是更改我使用的图像按钮的代码(drawable / dbmdtndeck.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected -->
<item android:drawable="@drawable/ydeck2"
android:state_selected="true"
android:state_focused="true"
android:state_pressed="true" />
<!-- When not selected -->
<item android:drawable="@drawable/ydeck" />
</selector>
这是我使用的文件存储在布局文件夹(layout / frmdbm.xml)中:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

这是我的java类代码(dbm.java):
package com.example.yao;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
/* FOR TOAST (POP MESSAGE), BUTTON, AND IMAGE BUTTON*/
import android.app.AlertDialog;
import android.widget.Button;
import android.widget.Gallery;
import android.widget.Toast;
import android.widget.ImageButton;
/* FOR TAB RESOUCE */
import android.app.TabActivity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.res.Resources;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class dbm extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.frmdbm);
/* Calling TOAST MESSAGE
*
*
*/
addListenerOnButton();
}
/* TOAST MESSAGE (POP MESSAGE)
*
*/
public void addListenerOnButton() {
/*
* ASSINING OBJECTS TO BUTTON VERIABLES
*/
ImageButton imageButtonedit = (ImageButton) findViewById(R.id.imgbtnedit);
ImageButton imageButtondeck = (ImageButton) findViewById(R.id.imgbtndeck);
ImageButton imageButtonwish = (ImageButton) findViewById(R.id.imgbtnwish);
ImageButton imageButtonsearch = (ImageButton) findViewById(R.id.imgbtnsearch);
ImageButton imageButtonrestrict = (ImageButton) findViewById(R.id.imgbtnrestrict);
/*
* WHEN CLICK ON THE OBJECT POP MESSAGE APPEARS
*/
imageButtonedit.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
Toast.makeText(dbm.this,
"DECK EDITOR", Toast.LENGTH_SHORT).show();
}
});
imageButtondeck.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
Toast.makeText(dbm.this,
"DECK RECEPICES", Toast.LENGTH_SHORT).show();
}
});
imageButtonwish.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
Toast.makeText(dbm.this,
"WISH LIST", Toast.LENGTH_SHORT).show();
}
});
imageButtonsearch.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
Toast.makeText(dbm.this,
"CARD SEARCHER", Toast.LENGTH_SHORT).show();
}
});
imageButtonrestrict.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
Toast.makeText(dbm.this,
"FORBIDDEN / LIMITED LIST", Toast.LENGTH_SHORT).show();
}
});
}
}
此外,我需要说这个布局(frmdbm.xml)被调用到一个framelayout,我在我的activity_main.xml中调用了tabcontent。当用户使用相应的选项卡时,该布局(frmdbm.xml)将出现在framelayout中。另外,我没有得到任何错误,但我注意到它没有改变图像,它保留原始图像。我是这个Android开发人员的新手,我不确定是怎么回事,因为我对我的标签做了这个,它似乎工作得很好。不知道我在这里做了什么不同。
谢谢

使用此:
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/button_idle"
android:state_focused="false"
android:state_pressed="false"
android:state_selected="false"/>
<item android:drawable="@drawable/button_pressed"
android:state_focused="false"
android:state_pressed="true"
android:state_selected="false"/>
</selector>

尝试将此作为选择器......
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:drawable="@drawable/learn" />
<item android:drawable="@drawable/learng" />
</selector>

试试..
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_selected="true" android:drawable="@drawable/buttonpress"/>
<item android:state_focused="true" android:drawable="@drawable/buttonpress"/>
<item android:state_pressed="true" android:drawable="@drawable/buttonpress"/>
<item android:drawable="@drawable/button"/>
</selector>
