我刚刚发现我无法删除,即使我设置了2个按键之间的空间layout_marginRight和layout_marginLeft下面.但是如果我将空间设置得更大,例如10 dp,那就更有意义了.有什么方法可以解决吗？

Android:如何设置ImageButton图像的高度/宽度(src图像背景的内容)？
我想设置顶层图像(不是背景)图像的高度/宽度,应该自定义图像的大小而不是自动填充按钮
我需要创建一个按钮,左边有一个图标,右边有一个文本.按下按钮后,我想在按钮左侧图标的位置看到旋转图像的动画.
我试图使用AnimationDrawable,但它也没有用,没有动画但只显示了第一个png文件.无论我使用什么背景或leftDrawable按钮来运行AnimationDrawable都是一样的.代码如下:
package com.example.layout;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.Button;
public class TestLinearlayoutActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onStart() {
super.onStart();
Button locationTitleButton = (Button) findViewById(R.id.LocationTitleButton);
//locationTitleButton.setBackgroundResource(R.drawable.loading);
locationTitleButton.setCompoundDrawablesWithIntrinsicBounds(R.drawable.loading, 0, 0, 0);
Drawable[] locationTitleButtonDrawables = locationTitleButton.getCompoundDrawables();
AnimationDrawable animDrawable = (AnimationDrawable) locationTitleButtonDrawables[0];
//AnimationDrawable animDrawable = (AnimationDrawable) locationTitleButton.getBackground();
animDrawable.start();
}
}
//loading.xml:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item …我在测试apdater的getView时遇到了错误.测试代码在测试用例期间调用View.setImageResource(0)以在异常发生时设置空图像.
我用Eclipse运行了测试robolectric-2.2-20130712.161723-17-jar-with-dependencies.jar.我尝试用ShadowResources.createFor(new ResourceLoader(){...}替换ResouceLoader.但是它不起作用.我没有调用我替换的ResouceLoader.
有人知道怎么解决吗？

我的Apdater ContentDetailsAdapter上的roboletric单元测试中的另一个类似问题来自语句mContext.getResources().getString(R.string.delete_hint_title).mContext由Robolectric.getShadowApplication().getApplicationContext()创建.关于Roboletric我的配置有问题吗？我能够在单元测试中调用ProgressDialog.show(mContext,"","").似乎问题总是与资源有关.这是堆栈:
