[Android] Use ActivityGroup to switch between Activity and Layout

Preface

In a main interface, TabActivity is usually used for Activity switching, which is convenient to use. The Activity is relatively independent from each other, but the customization is not strong, and it is difficult to modify. Of course, you can also separate layout and write all the logic code in the logic code on the main interface, but it is obvious that the maintainability is quite poor. ActivityGroup is used to solve this problem.

Body

I,

　　　　

You must click the different image buttons at the bottom to switch between different activities and display the ContentView of the Activity in the middle.

 

II. Implementation Code

2.1 layout. xml

<? Xml version = "1.0" encoding = "UTF-8"?>
<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Android: layout_width = "fill_parent" android: orientation = "vertical"
Android: layout_height = "fill_parent">
<LinearLayout android: gravity = "center_horizontal"
Android: background = "@ drawable/myinfor2" android: layout_width = "fill_parent"
Android: layout_height = "wrap_content">
<TextView android: id = "@ + id/cust_title" android: textColor = "@ android: color/white"
Android: textSize = "28sp" android: text = "Module 1" android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"> </TextView>
</LinearLayout>
<! -- Dynamically load View in the middle -->
<ScrollView android: measureAllChildren = "true" android: id = "@ + id/containerBody"
Android: layout_weight = "1" android: layout_height = "fill_parent"
Android: layout_width = "fill_parent">
</ScrollView>
<LinearLayout android: background = "@ android: color/black"
Android: layout_gravity = "bottom" android: orientation = "horizontal"
Android: layout_width = "fill_parent" android: layout_height = "wrap_content">
<! -- Function module button 1 -->
<ImageView android: id = "@ + id/btnModule1" android: src = "@ android: drawable/ic_dialog_dialer"
Android: layout_marginLeft = "7dp" android: layout_marginTop = "3dp"
Android: layout_marginBottom = "3dp" android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"/>
<! -- Function module button 2 -->
<ImageView android: id = "@ + id/btnModule2" android: src = "@ android: drawable/ic_dialog_info"
Android: layout_marginLeft = "7dp" android: layout_marginTop = "3dp"
Android: layout_marginBottom = "3dp" android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"/>
<! -- Function module button 3 -->
<ImageView android: id = "@ + id/btnModule3" android: src = "@ android: drawable/ic_dialog_alert"
Android: layout_marginLeft = "7dp" android: layout_marginTop = "3dp"
Android: layout_marginBottom = "3dp" android: layout_width = "wrap_content"
Android: layout_height = "wrap_content"/>
</LinearLayout>
</LinearLayout>

2.2 TestView. java

/**

* @ Author: farmer's uncle

*/
Public class TestView extends ActivityGroup {

Private ScrollView container = null;

@ Override
Protected void onCreate (Bundle savedInstanceState ){
Super. onCreate (savedInstanceState );
// Hide the title bar
RequestWindowFeature (Window. FEATURE_NO_TITLE );
// Set the view
SetContentView (R. layout. layout );

Container = (ScrollView) findViewById (R. id. containerBody );

// Module 1
ImageView btnModule1 = (ImageView) findViewById (R. id. btnModule1 );
BtnModule1.setOnClickListener (new OnClickListener (){
@ Override
Public void onClick (View v ){
Container. removeAllViews ();
Container. addView (getLocalActivityManager (). startActivity (
"Module1 ",
New Intent (TestView. this, ModuleView1.class)
. AddFlags (Intent. FLAG_ACTIVITY_CLEAR_TOP ))
. GetDecorView ());
}
});

// Module 2
ImageView btnModule2 = (ImageView) findViewById (R. id. btnModule2 );
BtnModule2.setOnClickListener (new OnClickListener (){
@ Override
Public void onClick (View v ){
Container. removeAllViews ();
Container. addView (getLocalActivityManager (). startActivity (
"Module2 ",
New Intent (TestView. this, ModuleView2.class)
. AddFlags (Intent. FLAG_ACTIVITY_CLEAR_TOP ))
. GetDecorView ());
}
});

// Module 3
ImageView btnModule3 = (ImageView) findViewById (R. id. btnModule3 );
BtnModule3.setOnClickListener (new OnClickListener (){
@ Override
Public void onClick (View v ){
Container. removeAllViews ();
Container. addView (getLocalActivityManager (). startActivity (
"Module3 ",
New Intent (TestView. this, ModuleView3.class)
. AddFlags (Intent. FLAG_ACTIVITY_CLEAR_TOP ))
. GetDecorView ());
}
});
}
}

Code Description:

A). ModuleView1, ModuleView2, and ModuleView3 inherit from Activity respectively.

B) To dynamically change the title, you can use cust_title to obtain TextView and set it.

I have been busy some time ago (in fact, I am also very busy now--#). This problem has been bothering me for a long time and is finally solved.
