安装旧版本的Elasticsearch(Installing older version of Elasticsearch)

 让我们为你做一些代码案例...... :)为了将动态样式应用到你的视图（在这种情况下是按钮），你必须在你的布局文件夹（res / layout）中执行以下操作。 
 
 我将它命名为buttonstyle.xml 
 
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true">
        <shape>
            <solid android:color="#449def"/>
            <stroke android:width="1dp" android:color="#2f6699"/>
            <corners android:radius="3dp"/>
            <padding android:left="10dp" android:top="10dp" android:right="10dp"
                     android:bottom="10dp"/>
        </shape>
    </item>

    <item>
        <shape>
            <gradient android:startColor="#449def" android:endColor="#2f6699" android:angle="270"/>
            <stroke android:width="1dp" android:color="#2f6699"/>
            <corners android:radius="4dp"/>
            <padding android:left="10dp" android:top="10dp" android:right="10dp"
                     android:bottom="10dp"/>
        </shape>
    </item>

</selector>
 
 现在将样式应用于您的按钮，将以下代码添加到您活动的onCreate（）方法中。 
 
Button transferBtn = new Button(this);
transferBtn.setText("Test Example");
transferBtn.setId(R.string.transferBtn);
transferBtn.setBackgroundResource(R.layout.buttonstyle);

Let's do some code for you case...:) For applying style to your view (button in this case) dynamically is you have to do the following in your layout folder (res/layout). 
 
I named it as,buttonstyle.xml
 
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true">
        <shape>
            <solid android:color="#449def"/>
            <stroke android:width="1dp" android:color="#2f6699"/>
            <corners android:radius="3dp"/>
            <padding android:left="10dp" android:top="10dp" android:right="10dp"
                     android:bottom="10dp"/>
        </shape>
    </item>

    <item>
        <shape>
            <gradient android:startColor="#449def" android:endColor="#2f6699" android:angle="270"/>
            <stroke android:width="1dp" android:color="#2f6699"/>
            <corners android:radius="4dp"/>
            <padding android:left="10dp" android:top="10dp" android:right="10dp"
                     android:bottom="10dp"/>
        </shape>
    </item>

</selector>
 
Now apply style to your button, add the following code to onCreate() method of your activity..
 
Button transferBtn = new Button(this);
transferBtn.setText("Test Example");
transferBtn.setId(R.string.transferBtn);
transferBtn.setBackgroundResource(R.layout.buttonstyle);
