Android Phone defender--home Interface layout

This article realizes when enters the hone interface from the splash interface, produces a gradual fade in the animation effect, calls a method Initanimation () in the OnCreate, the code is as follows:

    /**      * Add fade-in animation     effect *     /privatevoid  initanimation (        ) {  New alphaanimation (0, 1);        Alphaanimation.setduration (+);        Rl_root.startanimation (alphaanimation);    }

Where rl_root is defined in the class

Private Relativelayout Rl_root;

Where Rl_root is the id:android:id= "@+id/rl_root" of the relative layout of the splash interface

Then add the appropriate code in the Initialize UI method

    /**      * Initialize UI method     alt+shift+j*    /privatevoid  Initui () {        = (TextView) Findviewbyid (r.id.tv_version_name);          =   (relativelayout) Findviewbyid (r.id.rl_root);    }

This achieves the fade-in effect of the splash interface.

The next step to implement the home interface, the first implementation is the title bar, the effect is as follows:

The code is as follows:

  <TextViewAndroid:text= "Feature List"android:gravity= "Center"android:textsize= "20SP"Android:textcolor= "#000"android:padding= "10DP"Android:background= "#0f0"Android:layout_width= "Match_parent"Android:layout_height= "Wrap_content" />

However, because the style of the title bar is very common, all write it as a style wrapper for immediate invocation later, then add the following code in the Style.xml file:

    <stylename= "TitleStyle">        <Itemname= "Android:gravity">Center</Item>        <Itemname= "Android:textsize">20sp</Item>        <Itemname= "Android:textcolor">#000</Item>        <Itemname= "Android:padding">10dp</Item>        <Itemname= "Android:background">#0f0</Item>        <Itemname= "Android:layout_width">Match_parent</Item>        <Itemname= "Android:layout_height">Wrap_content</Item>    </style>

This requires only a simple invocation in the Activity_home.xml:

    < TextView         Android:text = "Feature List"         style= "@style/titlestyle"/>
