自定义 标题栏

先创建一个标题栏的类，需要用到 foot_bar_item.xml 和 FootBarActionParmater类。

package pageview.footBar;import android.content.Context;import android.graphics.Color;import android.util.AttributeSet;import android.util.DisplayMetrics;import android.view.LayoutInflater;import android.view.View;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TextView;import com.example.lin_ling.mynfcapplication01.R;import java.util.ArrayList;import java.util.List;/** * Created by ty-deng on 17/5/6. */public class FootBar extends LinearLayout {    Context context;    List<FootBarActionParmater> dataScoure = new ArrayList<FootBarActionParmater>();    ActionParmaterListener listener;    int  selectPosition = 0;    public interface ActionParmaterListener{        void ActionListener(int position);    }    public FootBar(Context context) {        super(context);        this.context = context;    }    public FootBar(Context context, AttributeSet attrs) {        super(context, attrs);        this.context = context;    }    public FootBar(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        this.context = context;    }    public void setFootBarActionParmater(List<FootBarActionParmater> dataScoure,ActionParmaterListener mlistener){        this.dataScoure = dataScoure;        this.listener = mlistener;        setOrientation(LinearLayout.HORIZONTAL);        DisplayMetrics dm = getResources().getDisplayMetrics();        int width = dm.widthPixels/dataScoure.size();        for (int i = 0;i<dataScoure.size();i++){            final FootBarActionParmater parmater = dataScoure.get(i);            LayoutInflater layoutInflater = LayoutInflater.from(context);            LinearLayout linearLayout = (LinearLayout) layoutInflater.inflate(R.layout.foot_bar_item,null);            linearLayout.setLayoutParams(new LayoutParams(width,LayoutParams.WRAP_CONTENT));            final ImageView imageView = (ImageView)linearLayout.findViewById(R.id.imageView1);            imageView.setImageResource(parmater.imageNameResourceId);            final TextView barView = (TextView) linearLayout.findViewById(R.id.textView1);            barView.setTextColor(Color.WHITE);            barView.setText(parmater.title);            final int position = i;            parmater.imageView = imageView;            parmater.barview = barView;            linearLayout.setOnClickListener(new View.OnClickListener(){                @Override                public void onClick(View view) {                    if(listener != null){                        selectBar(position);                        listener.ActionListener(position);                    }                }            });            addView(linearLayout);        }    }    public void selectBar(int positon){        FootBarActionParmater parmater = dataScoure.get(selectPosition);        parmater.imageView.setImageResource(parmater.imageNameResourceId);        FootBarActionParmater parmaterSelect = dataScoure.get(positon);        parmaterSelect.imageView.setImageResource(parmaterSelect.imageNameResourceIdSelected);        selectPosition = positon;    }    public int  getResource(String imageName){        int resId = getResources().getIdentifier(imageName, "drawable", context.getPackageName());        //如果没有在"mipmap"下找到imageName,将会返回0        return resId;    }}

FootBarActionParmater类

package pageview.footBar;/** * Created by ty-deng on 17/5/6. */public class FootBarActionParmater{    public String title;    public int imageNameResourceId;    public int imageNameResourceIdSelected;    public ImageView imageView;    public TextView barview;    public FootBarActionParmater(String title,int imageNameResourceId,int imageNameResourceIdSelected){        this.title =title;        this.imageNameResourceId = imageNameResourceId;        this.imageNameResourceIdSelected = imageNameResourceIdSelected;    }}

foot_bar_item.xml布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:orientation="vertical"    android:layout_width="wrap_content"    android:layout_height="wrap_content">        <ImageView            android:layout_width="25sp"            android:layout_height="25sp"            android:layout_gravity="center_horizontal"            android:paddingTop="5sp"            android:layout_marginTop="5sp"            android:id="@+id/imageView1" />        <TextView            android:text="TextView"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:padding="5sp"            android:layout_gravity="center_horizontal"            android:gravity="center"            android:id="@+id/textView1" /></LinearLayout>

使用布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/activity_main2"    android:layout_width="match_parent"    android:background="@drawable/blue_background_change"    android:layout_height="match_parent">    <include layout="@layout/my_title_bar"        android:id="@+id/include" />    <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:id="@+id/contectView"        android:orientation="vertical">        <pageview.footBar.FootBar            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:background="#fff4f4f4"            android:id="@+id/footbar">        </pageview.footBar.FootBar>    </LinearLayout></RelativeLayout>

代码使用使用

  FootBar footBar = (FootBar) findViewById(R.id.footbar);        List<FootBarActionParmater> dataScoure = new ArrayList<FootBarActionParmater>(); FootBarActionParmater fooBar = new FootBarActionParmater("防伪查询",R.drawable.blue_background_change);        dataScoure.add(fooBar);        FootBarActionParmater fooBar1 = new FootBarActionParmater("授权查询",R.drawable.blue_background_change);        dataScoure.add(fooBar1);        FootBarActionParmater fooBar2 = new FootBarActionParmater("后台",R.drawable.blue_background_change);        dataScoure.add(fooBar2);        footBar.setFootBarActionParmater(dataScoure, new FootBar.ActionParmaterListener() {            @Override            public void ActionListener(int position, ImageView imageView, TextView barView) {            }        });
