Android界面 - 什么部件使用需求建议 [英] Android interface - need suggestions on what widgets to use

问题描述

我需要创建界面，看起来像秩序。所以，会有头数据，然后会出现的细节。我认为这是所有滚动屏幕。但我不知道什么是最好的方式来绑定细节。

I need to create interface that will look like "order". So, there will be header data and then there will be details. I see it as all scrollable screen. But I'm not sure what the best way to bind details.

我可以看到我怎么可以：

I can see how I can:

1. 创建ListView和在第一排放头 - IMO UGLY code

1. Create ListView and put header in first row - IMO UGLY code.

创建ListActivity，顶部和下面的ListView放头 - 没有好或者因为头不会滚动

Create ListActivity, put header on top and ListView below - no good either since header won't scroll.

我不知道怎么做，但想法是创建主要布局，并把空的LinearLayout细节的地方应该是。然后创建另一个布局的细节（就像我的ListView中做）。但是，我将加载的细节和手动充气的儿童的，然后将其注入到我的LinearLayout中。

I'm not sure HOW to do it but idea is to create main layout and put empty LinearLayout where details should be. Then create another Layout for details (just like I do for ListView). But I would load details and inflate those childs manually and then inject them into my LinearLayout.

请问这项工作？你会如何​​做其他类似的东西？

Will that work? How else would you do something like that?

谢谢！

推荐答案

最简单的解决办法是同时添加的TextView 和的ListView 在 RelativeLayout的。实际上，你可以替换 Textivew 任何查看（包括 ViewGorup ），你需要。

The simplest solution would be to add both a TextView and a ListView inside a RelativeLayout. You can actually replace the Textivew with any View (including a ViewGorup) you need.

请参阅如何实现它在本教程：的http://developer.android.com/resources/tutorials/views/hello-relativelayout.html

See how to implement it in this tutorial: http://developer.android.com/resources/tutorials/views/hello-relativelayout.html

，并检查罗曼盖伊的职位之间有很好的比较的LinearLayout 和 RelativeLayout的（和一般的善意的提醒）

and check also Romain Guy's posts for a nice comparison between LinearLayout and RelativeLayout (and good advise in general):

这是一个（非常简单）的方式来创建可扩展的LinearLayout 。当然，不是按钮，你会添加一些有趣的内容...

This is a (very simplified) way to create an expandable LinearLayout. Of course, instead of buttons, you will add some more interesting content...

• 文件 MyCustomControl.java

package com.aleadam.test;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MyCustomControl extends LinearLayout {
    Context context;
    Button upper, lower;
    TextView tv;

    public MyCustomControl(Context context) {
        super(context);
        this.context = context;
        expandLayout();
    }

    public MyCustomControl(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        expandLayout();
    }

    private void expandLayout() {
        setOrientation (VERTICAL);
        LayoutParams lp0 = new LayoutParams(
                 LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        LayoutParams lp1 = new LayoutParams(
                 LayoutParams.WRAP_CONTENT, 40);
        LayoutParams lp2 = new LayoutParams(
                 LayoutParams.WRAP_CONTENT, 200);
        TextView tv = new TextView(context);
        tv.setText("The title goes here");

        upper = new Button(context);
        upper.setText("Click to show the other button");

        lower = new Button(context);
        lower.setText("Click to hide this button");
        lower.setVisibility(GONE);

        upper.setOnClickListener(new OnClickListener () {
            public void onClick (View v) {
                lower.setVisibility(VISIBLE);               
            }
        });
        lower.setOnClickListener(new OnClickListener () {
            public void onClick (View v) {
                v.setVisibility(GONE);              
            }
        });      

        this.addView(tv, lp0);
        this.addView(upper, lp1);
        this.addView(lower, lp2);
    }
}

• 文件 Test.java



public class Test extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        inflateLayout();
    }
    public void inflateLayout() {
        ScrollView scr = new ScrollView (this);
        LinearLayout ll = new LinearLayout (this);
        ll.setOrientation(LinearLayout.VERTICAL);
        ll.addView (new MyCustomControl (this));
        ll.addView (new MyCustomControl (this));
        ll.addView (new MyCustomControl (this));
        ll.addView (new MyCustomControl (this));
        scr.addView(ll);
        setContentView (scr);
    }
}
