I am making an app with a sliding menu on the left (see http://mobile.tutsplus.com/tutorials/appcelerator/titanium-mobile-create-a-sliding-menu-for-ios/). And I'm trying to add a background to the rows, but every time I try that and I start the simulator, the background can only be seen a little bit because there's a white background behind the title of the row for some reason. Here's the code:
var menuTitles = [
{title: 'Home', backgroundImage: "images/row_BG.png", id: 1},
{title: 'Vestigingen', height: 30, font:{fontSize: 14, fontWeight: "bold", fontFamily: "Helvetica"}},
{title: 'Han Fortmann', backgroundImage: "images/row_BG.png", leftImage: 'images/HF_Logo_#2x.png', id: 2, font:{fontSize: 14, fontWeight: "normal", fontFamily: "Helvetica"}},
{title: 'Johannes B.', leftImage: 'images/JB_Logo_#2x.png', id: 3, font:{fontSize: 14, fontWeight: "normal", fontFamily: "Helvetica"}}
];
Maybe you should precise the Titanium version you're using to get more accurate answers.
Nevertheless, I think the answer you're looking for is the backgroundColor: 'transparent' property. Try this, and it should work :
{backgroundColor: 'transparent', title: 'Home', backgroundImage: "images/row_BG.png", id: 1}

I have an echart with a serie type:'custom' and I have a rendering issues on the labels.
I return this
return {
type: 'group',
children: [
{
type: 'rect',
ignore: !rectNormal,
shape: rectNormal,
style: { stroke: '#707070' }
},
{
type: 'rect',
ignore: !rectText,
shape: rectText,
strokeLinejoin: "round",
stroke: 'trasparent',
strokeWidth: 0,
style: api.style({
fill: 'transparent',
fontWeight: bigText? 600 : 100,
fontSize: bigText? 15 : 10,
textStroke: '#707070',
strokeLinejoin: "round",
strokeLinecap: "round",
textStrokeWidth: 3,
text: text,
textFill: '#ffffff'
})
}
]
And it' rendered like this
As you can see the text stroke have problem in rendering the M letters and the strokeLinejoin and strokeLinecap did not solve the problem.
Do someone know how to fix this?
I solved it this way
{
type: 'rect',
ignore: !rectText,
shape: rectText,
strokeLinejoin: "round",
stroke: 'trasparent',
strokeWidth: 0,
style: api.style({
fill: 'transparent',
fontWeight: bigText? 600 : 100,
fontSize: bigText? 15 : 10,
textStroke: '#707070',
lineJoin: "bevel",
textStrokeWidth: 3,
text: text,
textFill: '#ffffff'
})
}
I'm attempting a theme type system, where i can create themes as json files, and then style my app based on it. For the most part all of it works except 2 parts for some reason,
Text Color
Background Colors
So everything else is styled correctly, but the backgroundColor and text colors just wont for some reason. I have checked multiple times over that the theme's values are available, console.log prints them fine too. There's no error message, and other styling from the theme works fine.
Here's where i load in the themes
const themes = {
DEFAULT: require('./../assets/themes/default.json')
};
let theme = {};
function loadDefaultTheme() {
parseTheme(themes.DEFAULT);
}
function parseTheme(json) {
theme.name = json.name;
theme.backgroundColor = json.backgroundColor;
theme.navBackgroundColor = json.navBackgroundColor;
theme.blueColor = json.blueColor;
theme.redColor = json.redColor;
theme.darkBlueColor = json.darkBlueColor;
theme.placeholderColor = json.placeholderColor;
theme.buttonTextColor = json.buttonTextColor;
theme.textColor = json.textColor;
theme.iconColor = json.iconColor;
theme.iconActiveColor = json.iconActiveColor;
theme.navTextColor = json.navTextColor;
theme.navActiveTextColor = json.navActiveTextColor;
}
module.exports = {
themes: themes,
theme: theme,
loadDefaultTheme: loadDefaultTheme,
parseTheme: parseTheme
};
Here's my styling
const welcomeStyles = StyleSheet.create({
background: {
flex: 1,
width: Info.WINDOW_WIDTH,
height: Info.WINDOW_HEIGHT
},
logo: {
width: '50%',
height: '50%',
alignSelf: 'center'
},
text: {
color: ThemeParser.theme.textColor,
alignSelf: 'center',
fontFamily: 'Arial',
},
appNameText: {
fontWeight: 'bold',
fontSize: 30,
marginTop: -60
},
descText: {
fontSize: 22
},
loginView: {
width: Info.WINDOW_WIDTH,
height: Info.WINDOW_HEIGHT * 0.6,
backgroundColor: ThemeParser.theme.backgroundColor,
borderTopColor: '#FE5656', borderTopWidth: 4,
paddingTop: 25
}
});
Finally, my theme:
{
"name": "Default",
"backgroundColor": "#1D1D1D",
"navBackgroundColor": "#343434",
"blueColor": "#05b7ed",
"redColor": "#FF5757",
"darkBlueColor": "#047A9E",
"placeholderColor": "#545454",
"buttonTextColor": "white",
"textColor": "white",
"iconColor": "#047A9E",
"iconActiveColor": "#05B7ED",
"navTextColor": "#C1C1C1",
"navActiveTextColor": "white"
}
I have this bit elsewhere but this works for some reason...
<TouchableOpacity style={[global.globalStyles.halfButton, {backgroundColor: ThemeParser.theme.redColor}]} />
Edit: Components which the styles are not being applied. They work fine when i statically type a color like 'white' or '#1d1d1d'
<View style={styles.loginStyles.loginView}>
<Input
placeholder='Token'
placeholderTextColor={ThemeParser.theme.placeholderColor}
returnKeyType='done'
inputStyle={styles.loginStyles.token}
leftIcon={<Ionicons name='md-key' size={32} color={ThemeParser.theme.blueColor} />}
onChangeText={text => this.setState({token: text})}
/>
<View style={{flex: 1, justifyContent: 'flex-end'}}>
<View style={{flexDirection: 'row'}}>
<TouchableOpacity style={[global.globalStyles.halfButton, {backgroundColor: ThemeParser.theme.blueColor, borderRightColor: 'black', borderRightWidth: 4}]} onPress={() => AniListAuth.getALCode()}>
<Text style={global.globalStyles.buttonText}>Get Code</Text>
</TouchableOpacity>
<TouchableOpacity style={[global.globalStyles.halfButton, {backgroundColor: ThemeParser.theme.redColor}]} onPress={() => AniListAuth.login(this.state.token)}>
<Text style={global.globalStyles.buttonText}>Sign In</Text>
</TouchableOpacity>
</View>
</View>
The background color for the TouchableOpacity seems to work fine, but not for the View background color or Text color
Edit2: Here's a snack of the project thus far if my code above isn't as clear... http://snack.expo.io/Hk1_2AOtr
Check out the working snack.
This is because you are exporting the theme object before you are parsing it.
Your theme object is empty when you are exporting but you are parsing and adding properties to your object after it is exported which means you are calling themeParser.loadDefaultTheme() later in your code, by the time the empty theme object has already been exported.
It would be better if you use your themes object in your ThemeParser.js file:
const themes = {
DEFAULT: require('./../assets/themes/default.json')
};
module.exports = {
themes: themes,
theme: theme,
loadDefaultTheme: loadDefaultTheme,
parseTheme: parseTheme
};
and use it in GlobalStyles like so:
buttonText: {
color: ThemeParser.themes.DEFAULT.textColor,
fontWeight: 'bold',
fontSize: 20
}
And in WelcomeStyles like so:
text: {
color: ThemeParser.themes.DEFAULT.textColor,
alignSelf: 'center',
fontFamily: 'Arial',
},
loginView: {
width: Info.WINDOW_WIDTH,
height: Info.WINDOW_HEIGHT * 0.6,
backgroundColor: ThemeParser.themes.DEFAULT.backgroundColor,
borderTopColor: '#FE5656', borderTopWidth: 4,
paddingTop: 25
},
You can make the checks according to your needs when you want to load the themes object or theme object.
On react-native iOS, "react-native-linear-gradient": "^2.0.0".
After installing correctly this package with npm then using 'react-native link', i see a red border around my text but not any gradient with the example provided.
import LinearGradient from 'react-native-linear-gradient';
// Within your render function
<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
<Text style={styles.buttonText}>
Sign in with Facebook
</Text>
</LinearGradient>
// Later on in your styles..
var styles = StyleSheet.create({
linearGradient: {
flex: 1,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
buttonText: {
fontSize: 18,
fontFamily: 'Gill Sans',
textAlign: 'center',
margin: 10,
color: '#ffffff',
backgroundColor: 'transparent',
},
});
Please check this out

I have solved this problem from this blog.
Code Example :
<LinearGradient
colors={["#FFA500", "#C5121B"]}
start={{ x: 0, y: 0 }}
end={{ x: 1, y: 0 }}
style={{ borderRadius: 5 }}
>
<View style={styles.registerButtonStyle}>
<Text>Register</Text>
</View>
</LinearGradient>
registerButtonStyle: {
paddingLeft: 16,
paddingRight: 16,
paddingBottom: 7,
paddingTop: 7,
margin: 1,
backgroundColor: "white",
borderRadius: 5
},
Solved in my case with RN 0.41.2: run this command in the terminal 'react-native run-ios' for recompiling with xCode (necessary in general after a 'react-native link' command)
I need to change the space between lines in a text in a React Native for both android and iOS.
This is the code in the styles pages:
text: {
color: '#C0C0C0',
fontSize: 18,
textAlign: 'justify',
}
Use lineHeight -
text: {
color: '#C0C0C0',
fontSize: 18,
textAlign: 'justify',
lineHeight: 30,
},
You can use
{'\n'}
inside your Text tag
example :
<Text>{'\n'} Heading : </Text>
I want to use a layout where components are added horizontally like hbox but where upon adding if the component exceed the bounds of the container it is moved to the next line. This is similar to what FlowLayout is in swing and flex.
I couldn't find any layout in ExtJS 4.0 that would achieve this.
So I am wondering how I would go about doing this. I am fairly new to the framework so any pointers would be great.
Have you tried using ColumnLayout? If you don't specify the "columnWidth" properties, the child elements are css-floated from left to right:
Ext.create('Ext.Panel', {
width: 500,
height: 280,
title: "ColumnLayout Panel",
layout: 'column',
renderTo: document.body,
items: [{
xtype: 'panel',
title: 'First Inner Panel',
width: 250,
height: 90
},{
xtype: 'panel',
title: 'Second Inner Panel',
width: 200,
height: 90
}, {
xtype: 'panel',
title: 'Third Inner Panel',
width: 150,
height: 90
}]
});
