Gradle
Add below codes to your root build.gradle file (not your module build.gradle file).
allprojects {
repositories {
mavenCentral()
}
}
And add a dependency code to your module's build.gradle file.
dependencies {
implementation "com.github.skydoves:only:1.0.8"
}
Usage
Initialize
First, initialize the Only using init() method like below.
This code can be initialized on Application class only once.
Only.init(context)
onDo
Below codes will run the showIntroPopup() only three times using onDo method.
Only.onDo("introPopup", times = 3) {
showIntroPopup()
}
// kotlin dsl
only("introPopup", times = 3) {
onDo { showIntroPopup() }
}
Here is the Java codes.
Only.onDo("introPopup", 1, () -> showIntroPopup());
onDone
Below codes will run the doSomethingAfterDone() and toast("done") after run the onDo block codes three times.
Only.onDo("introPopup", times = 3,
onDo = {
showIntroPopup()
toast("onDo only three times")
},
onDone = {
doSomethingAfterDone()
toast("done")
})
// kotlin dsl
only("introPopup", times = 3) {
onDo {
showIntroPopup()
toast("onDo only three times")
}
onDone {
doSomeThingAfterDone()
toast("done")
}
}
Here is the Java codes.
Only.onDo("introPopup", 1,
() -> doSomethingOnlyOnce(), // onDo
() -> doSOmethingAfterDone() // onDone
);
onLastDo, onBeforeDone
We can do pre and post-processing using onLastDo, onBeforeDone options.
only("Intro", times = 3) {
onDo {
showIntroPopup()
toast("onDo only three times")
}
onLastDo { // executes only once after finished onDo block 3 times.
toast("finished onDo")
}
onBeforeDone { // executes only once before run onDone block.
toast("starts onDo")
}
onDone {
doSomethingAfterDone()
toast("done")
}
}
We can apply it for repeating x times.
Below codes shows review-popup 3 times and checks the user reviewed or not in onLastDo block.
If not, clear times using the Only.clearOnly method, and repeat it the first time again.
only("Intro", times = 3) {
onDo { showReviewRequestPopup() }
onLastDo { // executes only once after finished onDo block 3 times.
if (!isRequested) {
Only.clearOnly(this@only.name)
}
}
}
Version Control
We can renew the persistence times for controlling the version using version option.
If the version is different from the old version, run times will be initialized 0.
Only.onDo("introPopup", times = 3,
onDo = { showIntroPopup() },
onDone = { doSomethingAfterDone() },
version = BuildConfig.VERSION_NAME // we can set manually. e.g. "1.1.1.1"
)
// kotlin dsl
only("introPopup", times = 3) {
onDo { showIntroPopup() }
onDone { doSomethingAfterDone() }
version("1.1.1.1")
}
Create Using Builder
We can run Only using Only.Builder class like below.
Only.Builder("introPopup", times = 3)
.onDo { showIntroPopup() }
.onDone { doSomethingAfterDone() }
.version(BuildConfig.VERSION_NAME)
.run()
OnlyOnce, OnlyTwice, OnlyThrice
Here is some useful kotlin-dsl functions.
onlyOnce("onlyOnce") { // run the onDo block codes only once.
onDo { doSomethingOnlyOnce() }
onDone { doSomethingAfterDone() }
}
onlyTwice("onlyTwice") { // run the onDo block codes only twice.
onDo { doSomethingOnlyTwice() }
onDone { doSomethingAfterDone() }
}
onlyThrice("onlyThrice") { // run the onDo block codes only three times.
onDo { doSomethingOnlyThrice() }
onDone { doSomethingAfterDone() }
version("1.1.1.1")
}
Clear Data
We can optionally delete the stored Only target data or delete the whole Only data.
Only.clearOnly("introPopup") // clears a saved target Only data.
Only.clearAllOnly() // clears all of the target Only data on the application.
View Extension
Below codes will show the button view only once.
button.onlyVisibility(name = "myButton", times = 1, visible = true)
Toast Extension
Below codes will show toast only x times.
onlyToast("toast", 3, "This toast will be shown only three times.")
onlyOnceToast("toast1", "This toast will be shown only once.")
onlyTwiceToast("toast2", "This toast will be shown only twice.")
onlyThriceToast("toast3", "This toast will be shown only thrice.")
Marking
We can mark data to the Only target.
only("introPopup", times = 3) {
onDo { showIntroPopup() }
onDone { doSomethingAfterDone() }
mark("abc") // marks only once when run by kotlin dsl or builder class.
}
Only.mark("introPopup", 3) // changes marking using mark method.
val marking = Only.getMarking("introPopup") // gets the marked data.
Debug Mode
Sometimes on debug, we don't need to persist data and replay onDone block.
onlyOnDoDebugMode helps that ignore persistence data and onDone block when initialization. It runs only onDo block.
val only = Only.init(application)
if (BuildConfig.DEBUG) {
only.onlyOnDoDebugMode(true)
}
Usage in Java
Here are some usages for Java developers.
int times = Only.getOnlyTimes("IntroPopup") ;
if (times < 3) {
Only.setOnlyTimes("IntroPopup", times + 1);
showIntroPopup();
}
Java Supports
we can run Only in our java project.
Only.onDo("introPopup", 1,
new Runnable() {
@Override
public void run() {
doSomethingOnlyOnce();
}
}, new Runnable() {
@Override
public void run() {
doSOmethingAfterDone();
}
});
Or we can run using Only.Builder like below.
new Only.Builder("introPopup", 1)
.onDo(new Runnable() {
@Override
public void run() {
doSomethingOnlyOnce();
}
})
.onDone(new Runnable() {
@Override
public void run() {
doSOmethingAfterDone();
}
}).run(); // run the Only
Java8 lambda expression
We can make it more simple using Java8 lambda expression.
Add below codes on your build.gradle file.
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
Then you can run the Only like below.
Only.onDo("introPopup", 1,
() -> doSomethingOnlyOnce(), // onDo
() -> doSOmethingAfterDone() // onDone
);
Custom util class
We can create custom util class like what Kotlin's onlyOnce.
public class OnlyUtils {
public static void onlyOnce(
String name, Runnable runnableOnDo, Runnable runnableOnDone) {
new Only.Builder(name, 1)
.onDo(runnableOnDo)
.onDone(runnableOnDone)
.run(); // run the Only
}
}
