Menu Bar implementation at the bottom of Android
After reading ViewPager recently, I just wanted to make such a Demo. Of course, I also referred to the grid menu in the examples of experts and started to use the custom imgBtn, however, we found that the layout is not good on the pager tab, so it is best to select the GridView, which is simple and practical.
1. Master interface xml
Activity_main.xmlCopy codeThe Code is as follows: <RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Xmlns: tools = "http://schemas.android.com/tools"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: background = "@ drawable/bg"
Tools: context = ". MainActivity">
<Button
Android: id = "@ + id/btn_menu"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_alignParentTop = "true"
Android: layout_centerHorizontal = "true"
Android: text = "show/hide Menu"/>
<LinearLayout
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: layout_below = "@ + id/btn_menu"
Android: gravity = "center"
Android: orientation = "horizontal">
<Com. example. myMenu. MyImgBtn
Android: id = "@ + id/main_btn1"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_margin = "15dp"
Android: layout_weight = "1"/>
<Com. example. myMenu. MyImgBtn
Android: id = "@ + id/main_btn2"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_margin = "15dp"
Android: layout_weight = "1"/>
<Com. example. myMenu. MyImgBtn
Android: id = "@ + id/main_btn3"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_margin = "15dp"
Android: layout_weight = "1"/>
<Com. example. myMenu. MyImgBtn
Android: id = "@ + id/main_btn4"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_margin = "15dp"
Android: layout_weight = "1"/>
</LinearLayout>
<RelativeLayout
Android: id = "@ + id/layout_menu"
Android: layout_width = "match_parent"
Android: layout_height = "200dp"
Android: layout_alignParentBottom = "true">
<LinearLayout
Android: id = "@ + id/menu"
Android: layout_width = "match_parent"
Android: layout_height = "40dp"
Android: background = "# dd000000"
Android: gravity = "center">
<TextView
Android: id = "@ + id/TV _main"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_weight = "1"
Android: gravity = "center"
Android: text = "common"
Android: textColor = "# ffffffff"/>
<TextView
Android: id = "@ + id/TV _utils"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_weight = "1"
Android: gravity = "center"
Android: text = "tool"
Android: textColor = "# ffffffff"/>
<TextView
Android: id = "@ + id/TV _set"
Android: layout_width = "0dp"
Android: layout_height = "wrap_content"
Android: layout_weight = "1"
Android: gravity = "center"
Android: text = "Settings"
Android: textColor = "# ffffffff"/>
</LinearLayout>
<LinearLayout
Android: id = "@ + id/layout_anim"
Android: layout_width = "fill_parent"
Android: layout_height = "wrap_content"
Android: layout_below = "@ + id/menu"
Android: background = "# eeff8c00">
<ImageView
Android: id = "@ + id/iv_cursor"
Android: layout_width = "fill_parent"
Android: layout_height = "wrap_content"
Android: scaleType = "matrix"
Android: src = "@ drawable/img_cursor"/>
</LinearLayout>
<Android. support. v4.view. ViewPager
Android: id = "@ + id/myPager"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_below = "@ + id/layout_anim"
Android: flipInterval = "30"
Android: persistentDrawingCache = "animation"/>
</RelativeLayout>
</RelativeLayout>
Xml of the three tabs in ViewPager
View_main.xml, view_set.xml, view_utils.xmlCopy codeThe Code is as follows: <? Xml version = "1.0" encoding = "UTF-8"?>
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: background = "#77ff0000"
Android: orientation = "vertical">
<GridView
Android: id = "@ + id/myGridView"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: numColumns = "4"
Android: layout_margin = "10dp"
Android: horizontalSpacing = "20dp"
Android: gravity = "center"
Android: verticalSpacing = "20dp"
> </GridView>
</LinearLayout>
This is Tab 1 view_main.xml, and the other two are the same as this, so they will not be sent
Finally, there is a GirdView adapter xmlCopy codeThe Code is as follows: <? Xml version = "1.0" encoding = "UTF-8"?>
<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Xmlns: tools = "http://schemas.android.com/tools"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent">
<ImageView
Android: id = "@ + id/imgbtn_img"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_centerHorizontal = "true"
/>
<TextView
Android: id = "@ + id/imgbtn_text"
Android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"
Android: layout_below = "@ + id/imgbtn_img"
Android: layout_centerHorizontal = "true"
Android: text = "Text"
Android: textColor = "# ff0000ff"
Android: textSize = "10sp"/>
</RelativeLayout>
There are so many xml la S.
