I am trying to place a moveable TextView inside of an ImageView such that the TextView should listen to my touch movement and move accordingly but should remain within the borders of the ImageView.
I have the below XML code where I am using Github library ZoomageView:
`<?xml version="1.0" encoding="utf-8"?>

I am using the below function - isQuoteInsideImage() to get the location of my TextView w.r.t the ImageView :
`private boolean isQuoteInsideImage(float x, float y, ZoomageView view) {
int[] location = new int[2];
view.getLocationOnScreen(location);
int viewX = location[0];
int viewY = location[1];
return ((x > viewX && x < (viewX + view.getWidth())) && (y > viewY && y < (viewY + view.getHeight())));
}`
And the below code : `
moveQuoteText.setOnTouchListener((view, motionEvent) -> {
if (motionEvent.getAction() == MotionEvent.ACTION_MOVE) {
if (isQuoteInsideImage(moveQuoteText.getX(), moveQuoteText.getY(), editZoomageView)) {
view.setX(motionEvent.getRawX() - view.getWidth());
view.setY(motionEvent.getRawY() - view.getHeight());
}
}
return true;
});`
However, whenever I am trying to drag the TextView, the TextView goes out of the lower bounds and the Left Bounds. It however remains restricted at some distance from the upper bound.
Upper bound
Lower bound
What am I doing wrong and what should be done to make the TextView remain in the bound of the ImageView?

I have a listview inside constraint layout. When it has more lists, want to restrict the parent layout height. How can I set max layout height programmatically for bottom_layout? Display a maximum of 80% of device height.
This is the layout:
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/bottom_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<Button
android:id="#+id/try_again"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/primary_button"
android:minWidth="180dp"
android:text="#string/error_try_again"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
<ListView
android:id="#+id/instruction_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toTopOf="#+id/try_again"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/instruction_subtitle" />
<TextView
android:id="#+id/instruction_subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
<TextView
android:id="#+id/instruction_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/instruction_title"
app:layout_constraintBottom_toTopOf="#+id/instruction_subtitle"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Tried this solution on calling onCreate but didn't work:
private void BottomCardHeight(){
DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();
float density = metrics.density;
float device_height = metrics.heightPixels / density;
bottom_layout = findViewById(R.id.bottom_layout);
ConstraintSet set = new ConstraintSet();
set.clone(bottom_layout);
set.constrainMaxHeight(R.id.bottom_layout, (int) (device_height * 0.8));
// set.constrainHeight(R.id.bottom_layout, (int) (device_height * 0.8)); both not working
set.applyTo(bottom_layout);
//ConstraintLayout mConstrainLayout = (ConstraintLayout) findViewById(R.id.bottom_layout);
//ConstraintLayout.LayoutParams lp = (ConstraintLayout.LayoutParams) mConstrainLayout.getLayoutParams();
//lp.matchConstraintMaxHeight = (int) (device_height * 0.8);
//mConstrainLayout.setLayoutParams(lp);
}
You can you do this on layout by wrapping the ConstraintLayout in another one that has a height that matches the screen height.
Then add the below constraints to the inner ConstraintLayout to get a max height of 80% of the total screen height. This requires to have a height that match constraints
android:layout_height="0dp"
app:layout_constraintHeight_max="wrap"
app:layout_constraintHeight_percent="0.8"
So, the outer layouts would be:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottom_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_max="wrap"
app:layout_constraintHeight_percent="0.8"
app:layout_constraintStart_toStartOf="parent">
<!-- other views -->
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
I'm building an app using Constraint layout, but it has extra space bottom and top. I can't find where they come from. I checked maybe ten times from top to bottom all code but there is no margin or padding or anything else for it.

I tried adding guidelines to 0 points in the bottom but it also starts in that space. I gave -(minus) values to margin and padding but doesn't work. I don't know what else to do. You can see from screenshots how it looks.

Remove app:layout_constraintBottom_toTopOf="#id/guideline" from Brand and app:layout_constraintTop_toBottomOf="#id/LeftRight" from adView. You can't put constraints for Top and Bottom because it will center your View between those two constraints. Same about left and right (start, end), but you have match_parent here, so this problem doesn't occur (visualy - if you set wrap_content, view will go to the center too).
I am going to implement a progress bar with two clip textview on it.
Something like:
I use some trick (using paddingEnd/paddingStart, back/front textview to achieve the clip effect for textview) to implement it:
// part of activity
TextView leftFrontText;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View view = View.inflate(this, R.layout.test_page_layout, containerLayout);
View progressBar = view.findViewById(R.id.progress_bar);
leftFrontText = view.findViewById(R.id.left_front_textview);
int progress = 59;
ValueAnimator va = ValueAnimator.ofFloat(0f, progress);
int mDuration = 1000;
va.setDuration(mDuration);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
float value = (float)animation.getAnimatedValue();
setViewWidth(progressBar, (int)value);
setLeftFrontTextViewPadding((int)value);
}
});
// va.addListener(new Animator.AnimatorListener() {
// #Override
// public void onAnimationStart(Animator animation) {
//
// }
//
// #Override
// public void onAnimationEnd(Animator animation) {
// setLeftFrontTextViewPadding(progress);
// }
//
// #Override
// public void onAnimationCancel(Animator animation) {
//
// }
//
// #Override
// public void onAnimationRepeat(Animator animation) {
//
// }
// });
va.start();
}
private void setViewWidth(View view, int dp) {
ViewGroup.LayoutParams layoutParams = view.getLayoutParams();
layoutParams.width = ThemeUtil.dpToPx(this, dp);
view.setLayoutParams(layoutParams);
}
private void setLeftFrontTextViewPadding(int progressBarDp) {
int marginStart = ThemeUtil.dpToPx(TestPageActivity.this, 12);
leftFrontText.post(new Runnable() {
#Override
public void run() {
int textViewLength = leftFrontText.getWidth();
int progressbarDistance = ThemeUtil.dpToPx(TestPageActivity.this, progressBarDp);
if (textViewLength >= 0) {
int padding = marginStart + textViewLength - progressbarDistance;
leftFrontText.setPadding(0, 0, padding > 0 ? -padding : 0, 0);
}
}
});
}

When I run this code, it almost achieved the effect I want. But it has one issue. Textview keeps flashing while doing animation, and when animation finished, the color of textview sometime turn all white.
I think there may be something wrong in leftFrontText.post() of setLeftFrontTextViewPadding, like how I get width of textview. But I can't be quite sure. Can anyone show me the right way to do this? Or any other better way to implement this kind of progress bar.
Why not try this approach and leverage the power of ConstraintLayout as your progressBar:
<?xml version="1.0" encoding="utf-8"?>

android:layout_centerVertical="true"
android:gravity="center_vertical|end"
android:text="$0 / $0"
android:layout_alignRight="#id/left_front_textview"

</android.support.constraint.ConstraintLayout>
So basically we would have:
The Parent layout (parentview): having a fixed layout_width 360dp and contains the initial Grey TextViews
The Progress layout (progress_bar): also having a fixed size 360dp and contains the front White TextViews
Hence we overlay the Progress layout (progress_bar) ontop of its parent layout and increase or decrease the layout_width to simulate a progress without flickering:
The image below shows the progress layout having a static layout_width of 74dp; Also note that progress layout_width based on the example provided above can range from 1dp to max:360dp or otherwise 1% to 100% of parentview width.
So I have a layout file for a RecycleView which has expandable/collapsible viewholders.
Clicking on the header would expand/collapse the extra data. Everything looks fine in the editor. However, it would have a ghost space similar to layout_marginBottom.
First loaded appearance
Expanded
Collapsed correctly
So the editor would only display the ViewHolder as Figure 2 and 3.
However when running on a device, it would first display Figure 1, then after clicking on it to expand it, it would display Figure 2. Collapsing it once again would display Figure 3 instead of Figure 1. It would continue to display the correct figures (2 and 3).
The extra contents in Figure 2 have common parents with the header which is a ConstraintLayout.
This would happen regardless of the GONE specifiers: Programmatically or XML
Using activity.runOnUIThread would not help. Using a new Handler().onPostDelayed would only be worse as would display Figure 1 but with more unwanted space, as much as Figure 2, only without the extra info.

I had a very similar issue when attempting to hide elements when the keyboard is open
What would happen is when you open the keyboard you would get two resizes, One adjustment for the opening and the keyboard and another for setting the views to gone. The problem is the second adjustment would only occur when another element requests a layout so your screen would jump around very noticeably twice
When keyboard open
When you tap or move another UI element
I have found a solution for this, but only when Window soft input mode = adjust resize
See below
class MainActivity : AppCompatActivity() {
private var activityHeight = 0
private var keyboardOpen = false
private var mainScreen : ConstraintLayout? = null
private var infoText : TextView? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main_screen)
mainScreen = findViewById(R.id.mainConstraintLayout)
infoText = findViewById(R.id.mainInfoText)
//...
/* Capture initial screen size */
this#MainActivity.window.decorView.doOnNextLayout {
val displayFrame : Rect = Rect()
this#MainActivity.window.decorView.getWindowVisibleDisplayFrame(displayFrame)
activityHeight = displayFrame.height()
}
/* Check for keyboard open/close */
this#MainActivity.window.decorView.addOnLayoutChangeListener { v, left, top, right, bottom, oldLeft, oldTop, oldRight, oldBottom ->
val drawFrame : Rect = Rect()
this#MainActivity.window.decorView.getWindowVisibleDisplayFrame(drawFrame)
val currentSize = drawFrame.height()
if(keyboardOpen){
keyboardOpen = currentSize < activityHeight
if (!keyboardOpen){
infoText?.visibility = View.VISIBLE
}
}else {
keyboardOpen = currentSize < activityHeight
if(keyboardOpen) {
infoText?.visibility = View.GONE
/* Request a new layout on your base layout so screen adjusts correctly */
mainScreen?.requestLayout()
}
}
}
}
}
I find that there is a quick way to create animation with ConstraintSet for ConstrainLayout Activity. Faster than use TransitionManager for RelativeLayout
ConstraintSet use two xml file for an Activity. One for the first position and next one for the destination.
I want to create something like this:
https://media.giphy.com/media/2UwXdWEoLWe9iQMFIY/giphy.gif
But there is no clearly instruction show how to use it in Java. Anyone had done this can show me the source code or link to some post like that.
Thanks for reading the post.
This is possible with ConstraintSet. They key is two have two layouts one layout has ui elements of the screen and the other has elements on the screen. Now you can use TransitionManager with interpolator and duration of your choice and animate the layout changes.
