Espresso AppNotIdleException when using custom View

I have a problem when I test my login screen which has custom EditText in it. When I try run the test, the test always loading and nothing happen until I get AppNotIdleException. I'd disabled my system animation when run the test, and finally try remove my custom EditText view and the test running.
Here is my code:

Search bar appearing when swiping down in Kotlin

I'm building an Android app using Kotlin, I wanted to implement a search there but I want it somehow hidden (just like the search bar is in every iPhone), which will only show up if you swipe down. Can this actually be implemented in an android app?

Try the following code:
MainActivity.kt file:
package com.realtomjoney.searchbar_app
import android.animation.Animator
import android.animation.AnimatorListenerAdapter
import android.os.Bundle
import android.view.GestureDetector
import android.view.MotionEvent

import com.realtomjoney.searchbar_app.databinding.ActivityMainBinding
import kotlin.math.abs
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
private lateinit var detector: GestureDetectorCompat
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setBindings()
detector = GestureDetectorCompat(this, PrimaryGestureListener())
}
override fun onTouchEvent(event: MotionEvent?): Boolean {
return if (detector.onTouchEvent(event)) {
true
} else {
super.onTouchEvent(event)
}
}
inner class PrimaryGestureListener : GestureDetector.SimpleOnGestureListener() {
private val swipeThreshold = 100
private val swipeVelocityThreshold = 100
override fun onFling(
downEvent: MotionEvent?,
moveEvent: MotionEvent?,
velocityX: Float,
velocityY: Float
): Boolean {
val diffX = moveEvent?.x?.minus(downEvent!!.x) ?: 0.0F
val diffY = moveEvent?.y?.minus(downEvent!!.y) ?: 0.0F
if (abs(diffX) <= abs(diffY) &&
abs(diffY) > swipeThreshold && abs(velocityY) > swipeVelocityThreshold ) {
if (diffY > 0) {
this#MainActivity.binding.activityMainSearchViewTextInputLayout.alpha = 0f
this#MainActivity.binding.activityMainSearchViewTextInputLayout.visibility = View.VISIBLE
this#MainActivity.binding.activityMainSearchViewTextInputLayout
.animate()
.alpha(1f).setDuration(800)
.setListener(object : AnimatorListenerAdapter() {
override fun onAnimationEnd(animation: Animator) {
this#MainActivity.binding.activityMainSearchViewTextInputLayout.visibility =
View.VISIBLE
}
})
} else {
this#MainActivity.binding.activityMainSearchViewTextInputLayout
.animate()
.alpha(0f).setDuration(200)
.setListener(object : AnimatorListenerAdapter() {
override fun onAnimationEnd(animation: Animator) {
this#MainActivity.binding.activityMainSearchViewTextInputLayout.visibility =
View.GONE
}
})
}
}
return super.onFling(downEvent, moveEvent, velocityX, velocityY)
}
}
private fun setBindings() {
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
}
}

Feel free to adjust swipeThreshold swipeVelocityThreshold to your liking. The animations aren't the best, so I'd also recommend you change them.

Hamburger Icon not working in Android Studio

Hi so I got a code from Github and I customized it. The application doesn't have any navigation menus that's why I tried adding it myself(I have never made an application before so please be nice to me). So I tried following tutorials on Youtube on how to add navigation menus. I was successful in building one but when I tried to run it the hamburger icon doesn't seem to do anything. I probably messed up in the Main Activity but I can't seem to find the mistake. Please advise me. Thank you so much! The code of the application is below.

Here is my drawer_menu.xml

<item android:title="Profile" />
<item android:title="Follow us" />
<item android:title="Rate us" />
</menu>
Please help, I'm just new to android studio and kotlin, thank you so much.

Navigation menu should have menu items like this:
<item
android:id="#+id/home"
android:checked="true"
android:icon="#drawable/ic_home"
android:title="#string/home" />
And do this in the main Activity code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
NavigationView navView = findViewById(R.id.nav_view);
drawer = findViewById(R.id.drawer);
toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.open, R.string.close);
drawer.addDrawerListener(toggle);
navView.setNavigationItemSelectedListener(this);
}
Then add this callback to listen for menu item clicks:
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
}
This last part is very important:
#Override
protected void onPostCreate(Bundle state) {
super.onPostCreate(state);
toggle.syncState();
}
The SO post is useful in addition to this one.

ViewTreeObserver.OnGlobalLayoutListener on each and every recycler view items to passively resize TextView automatically

I have a plain basic recycler view and its adapter.In the single recycler view row, I got a textView which are floating numbers.The textView width length shall fixed in proportional sizes, i.e. 30 % of the screen.I want to put OnGlobalLayoutListener to auto resize text downward passively whenever the text exceed over the separator lineso that it fits in the textView box prepared.I don't want WRAP the numbers
So I add OnGlobalLayoutListener on each ViewHolder and expect to detect & tracing each row items if the costTextView is Overlapped to the separator line.
However what happened is it does not resize all rows, but part of items that exposed on user screen only. Example 4-7 does not affected, 8-12 is affected, so on.

This can be perfectly solved by the auto resizing feature of TextView
use something like this
<TextView
android:layout_width="100dp"
android:layout_height="40dp"
android:maxLines="1"
android:text="hello world google"
app:autoSizeTextType="uniform"
app:autoSizeMinTextSize="1sp"
app:autoSizeMaxTextSize="25sp"
android:gravity="center_vertical"
/>
