Android实现时间轴

昨天群里有讨论时间轴的项目,没有接触过,以为非常吊,研究之后才知道表面都是忽悠人的,使用listview就能实现了,也没有什么新奇的东西

废话少说,直接上图

图片和文字都能够私人订制

没什么好说的,直接上代码吧!相信你能看懂

1.时间轴item的布局文件

<?

xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <LinearLayout
        android:id="@+id/left"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <View
            android:layout_width="1dp"
            android:layout_height="25dp"
            android:layout_marginLeft="60dp"
            android:background="#A6A6A6" />

        <ImageView
            android:id="@+id/left_imageview"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="50dp"
            android:src="@drawable/medicalcheck2" />

        <View
            android:layout_width="1dp"
            android:layout_height="25dp"
            android:layout_marginLeft="60dp"
            android:background="#A6A6A6" />
    </LinearLayout>

    <LinearLayout
        android:layout_alignLeft="@id/left"
        android:layout_width="match_parent"
        android:layout_height="70dp"
        android:orientation="vertical"
        android:gravity="center"
        android:layout_marginLeft="100dp">

        <TextView
            android:id="@+id/right_textview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="aaa"/>
    </LinearLayout>

</RelativeLayout>

2.图片和文字的model

package com.sdufe.thea.guo.model;

public class TimeLineModel {

	private int imageview;
	private String text;

	public int getImageview() {
		return imageview;
	}

	public void setImageview(int imageview) {
		this.imageview = imageview;
	}

	public String getText() {
		return text;
	}

	public void setText(String text) {
		this.text = text;
	}

	public TimeLineModel(int imageview, String text) {
		super();
		this.imageview = imageview;
		this.text = text;
	}

}

3时间轴的适配器

package com.sdufe.thea.guo.adapter;

import java.util.List;

import com.sdufe.thea.guo.R;
import com.sdufe.thea.guo.model.TimeLineModel;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class TimeLineAdapter extends BaseAdapter {

	Context context;
	List<TimeLineModel> list;

	public TimeLineAdapter(Context context, List<TimeLineModel> list) {
		super();
		this.context = context;
		this.list = list;
	}

	@Override
	public int getCount() {
		if (list!=null) {
			return list.size();
		}
		return 0;
	}

	@Override
	public Object getItem(int position) {
		if (list!=null) {
			return list.get(position);
		}
		return null;
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ViewHold hold;
		if (convertView==null) {
			hold=new ViewHold();
			convertView=LayoutInflater.from(context).inflate(R.layout.timeline_item, null);
			convertView.setTag(hold);
		}else {
			hold=(ViewHold) convertView.getTag();
		}
		hold.imageView=(ImageView) convertView.findViewById(R.id.left_imageview);
		hold.show=(TextView) convertView.findViewById(R.id.right_textview);

		hold.imageView.setImageResource(list.get(position).getImageview());
		hold.show.setText(list.get(position).getText());
		return convertView;
	}

	static class ViewHold{
		public TextView show;
		public ImageView imageView;
	}

}

布局中的文件都跟listview的使用一样,也贴一下代码吧,方便你我他

package com.sdufe.thea.guo;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.Window;
import android.widget.ListView;

import com.sdufe.thea.guo.adapter.TimeLineAdapter;
import com.sdufe.thea.guo.model.TimeLineModel;

public class MainActivity extends Activity {

	private ListView listView;
	private List<TimeLineModel> list;
	private TimeLineAdapter adapter;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.activity_main);

		initData();
		initView();

	}

	private void initView() {
		listView=(ListView) findViewById(R.id.listview);
		adapter=new TimeLineAdapter(this, list);

		listView.setAdapter(adapter);
	}

	private void initData() {
		list=new ArrayList<TimeLineModel>();

		list.add(new TimeLineModel(R.drawable.medicalcheck2, "哈哈"));
		list.add(new TimeLineModel(R.drawable.nurse_visit2, "呵呵"));
		list.add(new TimeLineModel(R.drawable.nursingcareplan2, "嘿嘿"));
		list.add(new TimeLineModel(R.drawable.medicalcheck2, "哈哈"));
		list.add(new TimeLineModel(R.drawable.nurse_visit2, "啦啦"));
		list.add(new TimeLineModel(R.drawable.nursingcareplan2, "咳咳"));
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}

ok,代码上完了,不要被非常多app的外表唬住
