Question

我在线性布局中有一个textview。我将textview设置为match_parent，包括高度和宽度。

本质上，textview是屏幕的大小。但是文本与左上角保持一致。有没有办法让它居中？

我有android：gravity和android：textAlignment设置为居中。

<!doctype html>
<html>
<head>
    <title>Socket.IO</title>
</head>
<body>
<ul id="messages">
    <li>Hardcoded Message</li>
</ul>

<script src="/socket.io/socket.io.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
    var socket = io();
    socket.on("test-channel", function(message) {
        console.log(message);
        $('#messages').append($('<li>').text(message));
    });
</script>
</body>
</html>

Answer 1

使用

controllers.tests.js

或只是

describe('Controllers', function() { beforeEach(module('myApp.services', 'myApp.controllers')); var mockRequest = { } beforeEach(function() { module(function($provide) { $provide.value('initiateRequest', mockRequest); }); }); var $rootScope, $controller, $sharedProperties, $resource; beforeEach(inject(function(_$controller_, $rootScope) { myScope = $rootScope.$new(); $scope = {}; $state = {}; LoginService = {}; localStorageService = {}; sharedProperties = {}; $ionicLoading = myScope; initiateRequest = mockRequest; $controller = _$controller_; })); describe('$scope.login()', function() { it('does something', function() { var $scope = {}; var controller = $controller('LoginController', { $scope: $scope, $state: $state, LoginService: LoginService, localStorageService: localStorageService, sharedProperties: sharedProperties, $ionicLoading: $ionicLoading }); expect($scope.login).toBeDefined(true); expect($scope.show).toBeDefined(true); $scope.login(); }); }); });

将文本置于TexView中心。

编辑：尝试删除android:gravity="center_vertical|center_horizontal"或layout_weight属性
