Android Chart Library Mpandroidchart (14)--Using the same chart in a ListView type

You long time no see, recently very busy, all the blog updated relatively little, here today to say a relatively simple chart, that is, in the ListView using the same icon, because we will explain in the next article using different charts, the same chart is relatively simple, we look at

Specifically how to achieve, here we first write a cushion, for example, we need a base class activity

Viewpagerbaseactivity

 Packagecom.liuguilin.mpandroidchartsample.activity;/ * * Project name: Mpandroidchartsample * Package Name: com.liuguilin.mpandroidchartsample.activity * file name: Viewpagerbaseactivit Y * Created by: LGL * Created: 2016/12/13 16:28 * Description: TODO */ImportAndroid.os.Bundle;Importandroid.support.v4.app.FragmentActivity;ImportCOM.LIUGUILIN.MPANDROIDCHARTSAMPLE.R; Public Abstract  class viewpagerbaseactivity extends fragmentactivity {    protectedstring[] Mmonths =NewString[] {"Jan","The Feb","Mar","APR","may","June","Jul"," the","Sep","Okt","Nov","Dec"};protectedstring[] Mparties =NewString[] {"Party A","Party B","Party C","Party D","Party E","Party F","Party G","Party H","Party I","Party J","Party K","Party L","Party M","Party N","Party O","Party P","Party Q","Party R","Party S","Party T","Party U","Party V","Party W","Party X","Party Y","Party Z"};@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate); }protected float Getrandom(floatRangefloatStartsfrom) {return(float) (Math.random () * range) + Startsfrom; }@Override     Public void onbackpressed() {Super. onbackpressed ();    Overridependingtransition (r.anim.move_left_in_activity, r.anim.move_right_out_activity); }}

This base class is just as we use a lot of repetition of things including month and day conversion, we can ignore, we just need to use a method in this article, there are two of animation

Move_left_in_activity

<?xml version="1.0" encoding="utf-8"?><translate       xmlns:android="http://schemas.android.com/apk/res/android"      android:duration="300"      android:fromXDelta="-100%p"       android:toXDelta="0%p"></translate>

Move_right_out_activity

<?xml version="1.0" encoding="utf-8"?><translate       xmlns:android="http://schemas.android.com/apk/res/android"      android:duration="300"      android:fromXDelta="0%p"       android:toXDelta="100%p"></translate>

Is the simple translation of the animation, OK, we formally began to implement, in our XML, we just need to implement a ListView on the line

Activity_listview_char

<?xml version= "1.0" encoding= "Utf-8"?><linearlayoutxmlns:android="Http://schemas.android.com/apk/res/android"  Android:layout_width="Match_parent"android:layout_height="Match_parent"  Android:orientation="vertical">                    <ListViewandroid:id="@+id/mlistview"android:layout_width= "Match_parent" android:layout_height="match_parent"/>                        </linearlayout>

The logic is actually in the GetView of the adapter.

Can see, here we just implemented a ListView, in the adapter to write the implementation of my data, and then randomly 20 item on the OK, or quite simple, right, this is just a way of thinking, you can understand this, for our next article to do the groundwork, we will tell the next chapter is a different chart, That's dead end.
