This repo is a collection of sample data that you can use in your project. It also contains examples on how to improve preview of your layout.
Add following code into your build.gradle.
clean.doFirst {
println "cleanSamples"
def samplesDir = new File(projectDir.absolutePath, "sampledata")
if (samplesDir.exists()) {
samplesDir.deleteDir()
}
}
preBuild.doFirst {
println "fetchSamplesStarted"
def samplesDir = new File(projectDir.absolutePath, "sampledata")
if (samplesDir.exists()) {
println "samples dir already exists"
return
}
samplesDir.mkdir()
def files = ["lotr.json", "starwars.json", "hitchhikers.json", "developers.json"]
for(fileName in files) {
def names = new File(samplesDir, fileName)
new URL("https://raw.githubusercontent.com/VladimirWrites/tools-sample/master/sampledata/$fileName").withInputStream { i ->
names.withOutputStream {
it << i
}
}
println "fetchSample: $fileName"
}
println "fetchSamplesEnded"
}
After you rebuild your project, you will have files defined in files array in your sampledata folder.
Now you can use the sample data in your layout like this:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:text="@sample/lotr.json/characters/name" />
