我正在创建一个应用程序,其需求就像我有一个可以垂直滚动的列表,并且在该列表内,每个项目都有一个必须水平滚动的列表。所以我必须在水平滚动视图中设置该列表。我已经为该数据创建了一个自定义adpater,该数据在列表中显示一切正常,但是只有一个问题是列表垂直滚动,因为我无法将列表水平设置。请帮助我搜索了很多答案,但是没有用。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dp">
<android.support.v7.widget.CardView
android:id="@+id/card_view_applicant"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="3dp"
android:background="#fff"
app:cardCornerRadius="8dp"
app:cardElevation="1dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:id="@+id/tv_table_no"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="8dp"
android:text="T1"
android:textAlignment="center"
android:textColor=" #00008B"
android:textSize="25sp"
android:textStyle="bold" />
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#000000" />
</LinearLayout>
<HorizontalScrollView
android:id="@+id/hsv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:measureAllChildren="false"
android:scrollbars="none">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_marginLeft="50dp"
android:layout_height="match_parent">
<ListView
android:id="@+id/lv_timing"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>
</HorizontalScrollView>
</android.support.v7.widget.CardView>
</RelativeLayout>
</LinearLayout>
我试图做这样的事情,但这是行不通的,并且我不想使用任何recyclerview,我的要求很简单,我只想显示出这就是为什么。
答案 0 :(得分:1)
您必须使用RecyclerView进行水平滚动,例如:
// These are important and needed before anything else
import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import { enableProdMode } from '@angular/core';
import * as express from 'express';
import { join } from 'path';
// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();
// Express server
const app = express();
const PORT = process.env.PORT || 4000;
const DIST_FOLDER = join(process.cwd(), 'dist');
// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main');
// Express Engine
import { ngExpressEngine } from '@nguniversal/express-engine';
// Import module map for lazy loading
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';
app.engine('html', ngExpressEngine({
bootstrap: AppServerModuleNgFactory,
providers: [
provideModuleMap(LAZY_MODULE_MAP)
]
}));
app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));
// TODO: implement data requests securely
app.get('/api/*', (req, res) => {
res.status(404).send('data requests are not supported');
});
// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
// All regular routes use the Universal engine
app.get('*', (req, res) => {
res.render('index', { req });
});
// Start up the Node server
app.listen(PORT, () => {
console.log(`Node server listening on http://localhost:${PORT}`);
});

在android:layout_weight="1"
中使用ListView
。将LinearLayout
设为ListView
而不是RelativeLayout
的父布局,然后检查其是否有效。我认为应该可以。
<LinearLayout
..........>
<ListView
........
android:layout_weight="1"/>
</LinearLayout>
