为什么我们使用var themename = '{MY-THENE-NAME}';
var gulp = require('gulp'),
// Prepare and optimize code etc
autoprefixer = require('autoprefixer'),
flexboxfixer = require('postcss-flexboxfixer'),
browserSync = require('browser-sync').create(),
image = require('gulp-image'),
jshint = require('gulp-jshint'),
postcss = require('gulp-postcss'),
sass = require('gulp-sass'),
sourcemaps = require('gulp-sourcemaps'),
// Only work with new or updated files
newer = require('gulp-newer'),
// Name of working theme folder
root = '../' + themename + '/',
scss = root + 'sass/',
js = root + 'js/',
img = root + 'images/',
languages = root + 'languages/';
// CSS via Sass and Autoprefixer
gulp.task('css', function() {
return gulp.src(scss + '{style.scss,rtl.scss}')
.pipe(sourcemaps.init())
.pipe(sass({
outputStyle: 'expanded',
indentType: 'tab',
indentWidth: '1'
}).on('error', sass.logError))
.pipe(postcss([
flexboxfixer,
autoprefixer('last 2 versions', '> 1%')
]))
.pipe(sourcemaps.write(scss + 'maps'))
.pipe(gulp.dest(root));
});
// Optimize images through gulp-image
gulp.task('images', function() {
return gulp.src(img + 'RAW/**/*.{jpg,JPG,png}')
.pipe(newer(img))
.pipe(image())
.pipe(gulp.dest(img));
});
// JavaScript
gulp.task('javascript', function() {
return gulp.src([js + '*.js'])
.pipe(jshint())
.pipe(jshint.reporter('default'))
.pipe(gulp.dest(js));
});
// Watch everything
gulp.task('watch', function() {
browserSync.init({
open: 'external',
proxy: 'localhost/{MY-THENE-NAME}',
port: 8080
});
gulp.watch([root + '**/*.css', root + '**/*.scss' ], ['css']);
gulp.watch(js + '**/*.js', ['javascript']);
gulp.watch(img + 'RAW/**/*.{jpg,JPG,png}', ['images']);
gulp.watch(root + '**/*').on('change', browserSync.reload);
});
// Default task (runs at initiation: gulp --verbose)
gulp.task('default', ['watch']);
,请任何人解释一下吗?
在下面的代码ViewTreeObserver
中是creditsView
个对象。通过这整个代码,我理解“这是基于条件隐藏一些文本”,但只有我们使用TextView
的原因是什么?
ViewTreeObserver
答案 0 :(得分:5)
如果您没有使用ViewTreeObserver
,那么mainLayout.getRootView().getHeight()
只会返回0px,因为它尚未布局(请参阅getWidth()
and getHeight()
of View
returns 0)。
因此,您要等到视图被测量,布局,然后从中获取宽度/高度值。当视图将在屏幕上布局时,将完全触发此回调。

不知道为什么,但是这是我搜索KOTLIN时显示给我的第一页,并且在通过Lamda之后我无法删除列表器。
这就是我在科特林所做的事情
public static byte[] sign(byte[] file) throws Exception {
char password[] = "12345678".toCharArray();
Provider userProvider = new sun.security.pkcs11.SunPKCS11("C:\\ForJava\\eToken.cfg");
KeyStore ks = KeyStore.getInstance("PKCS11", userProvider);
ks.load(null, password);
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
Security.addProvider(userProvider);
//Working only with the first alias on the token
String alias = (String)ks.aliases().nextElement();
Signature signature = Signature.getInstance("SHA256withRSA");
PrivateKey privateKey = (PrivateKey) ks.getKey(alias, password);
signature.initSign(privateKey);
signature.update(file);
byte[] result = signature.sign();
//System.out.println("result coding: \n" +new BASE64Encoder().encode(result));
return result;
}
