Step 3: complete the navigation bar at the bottom of the android app

Many android applications have a bottom navigation bar at the bottom to facilitate User Switching during use. Currently, there are three common methods: Custom tabHost, activityGroup, and FrameLayout. After I have made multiple applications, I encapsulated an abstract class to save the development cycle. In three steps, I can generate the bottom column and call different pages.

Public class ActivitycollectiondemoActivity extends ActivityCollection {

/** Called when the activity is first created .*/

@ Override

Public void onCreate (Bundle savedInstanceState ){

Super. onCreate (savedInstanceState );

// SetBottomTabBackground (resId); // you can specify the background image of the bottom Navigation Pane.

}

@ Override

Protected boolean isShowWindowFeature (){

Return true; // set whether to display the title;

}

@ Override

Protected List SetDrawableCollections (){

List IndicatorInfos = new ArrayList ();

IndicatorInfo indicatorInfo_1 = new IndicatorInfo (R. drawable. baby1,

R. drawable. baby1_s, R. string. baby1, 12, Color. WHITE,

New Intent (ActivitycollectiondemoActivity. this,

Activity01.class ));

IndicatorInfo indicatorInfo_2 = new IndicatorInfo (R. drawable. baby2,

R. drawable. baby2_s, R. string. baby2, 12, Color. WHITE,

New Intent (ActivitycollectiondemoActivity. this,

Activity02.class ));

IndicatorInfo indicatorInfo_3 = new IndicatorInfo (R. drawable. baby3,

R. drawable. baby3_s, R. string. baby3, 12, Color. WHITE,

New Intent (ActivitycollectiondemoActivity. this,

Activity03.class ));

IndicatorInfo indicatorInfo_4 = new IndicatorInfo (R. drawable. baby4,

R. drawable. baby4_s, R. string. baby4, 12, Color. WHITE,

New Intent (ActivitycollectiondemoActivity. this,

Activity04.class ));

IndicatorInfos. add (indicatorInfo_1 );

IndicatorInfos. add (indicatorInfo_2 );

IndicatorInfos. add (indicatorInfo_3 );

IndicatorInfos. add (indicatorInfo_4 );

Return IndicatorInfos;

}

Step 1: import the jar package

Step 2: let your homeactivity inherit the ActivityCollection class

Step 3: add your image resources and jump intent to the list , Set the option

OK, an application containing the bottom navigation bar is ready. It is enough to deal with general applications. You can spend more time considering the business logic.
