I'm developing an app for users to share their books. To achieve this, I'm getting different data about the book from the user. The problem is, horizontal autoscrolling of all EditTexts are working until Dialog has been shown and dismissed. Once a dialog has been dismissed on the fragment, horizontal autoscrolling of the EditText's on this layout won't work.
I added:
android:focusable="true"
android:focusableInTouchMode="true"
to parent layout of the edittext but doesn't work.
Also to make sure that autoscrolling is enabled I've added:
android:scrollHorizontally="true"
But none of above helped.
Here is XML code of the fragment layout.

UI Design and Dialog
In the image above, there are EditTexts Name Of Book and Name of Author. Before showing a dialog, both of them work like a charm. When writing something, the cursor automatically scrolls to the end. Once Dialog has been shown and dismissed, none of them works properly, and the cursor stays at the end of the EditText but still the characters are being written continues in the hidden part.
In this UI it cannot be seen because of the issue, but I've written.

But only Roses are red, violets are blue, Stac can be seen.
Weird buggy layout UI image
Please, help me to solve this problem. Thanks in advance.
As a solution, I don't know the underlying reason, but the problem solved once I removed Butterknife library from my project.

In my Android application, I am attempting to programmatically add a custom TableRow view (CustomTableRow) to a TableLayout. CustomTableRow has cells of equal length (the first two cells have text, and the third one has a edit and delete button, as shown in the diagram below):
However, when I programmatically add a CustomTableRow to my TableLayout, this is the result I get (the cells are all jumbled together instead of occupying equal width):
This seems strange, considering that I have specified that all cells are to have weight 1 in the XML layout that CustomTableRow inflates. Furthermore, I even programatically set the cells in CustomTableRow to have weight 1 as an extra measure. And yet, the cells are still jumbled together.
Below is my code:

Thanks in Advance.
In this case the reason may be in StateDataItemBinding.
Is your root view in state_data_item.xml is clickable?
The app is supposed to call one screen from another and use the other screen's layout components. Whenever I try to call a component, such as ImageButton, it says that member id is unknown, I told my teacher and he says that it shouldn't happen. I have tried renaming the components and even made a new project.
How can I fix it?
the error is in R.id

I am making a simple app in which context view changes and then a toast message is displayed as input given by user. I don't understand why the app keeps on crashing when changing the context view.
Also Android studio gives this warning:
Method "Toaster" is missing in "FirstActivity" or has incorrect signature.
Here is my code:

MainScreen.java:
package com.example.nautatvanavlakha.abcd;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class MainScreen extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
}
public void toaster(View view){
EditText toast = (EditText)findViewById(R.id.toastText);
String final_toast = toast.getText().toString();
Toast.makeText(getApplicationContext(), final_toast, Toast.LENGTH_SHORT).show();
}
}
EDIT: As suggested, I moved the toaser function to FirstActivity.Java and deleted the MainScreen.java file as it becomes pointless to keep it. But the major problem is when I press the button (id named) the app keeps stopping.
EDIT2: I found that setContentView(R.layout.activity_main_screen) in FirstActivity.Java needs to be above this code
TextView textView = (TextView) findViewById(R.id.welcome);
textView.setText("Hi " + owner_string + ".");
Log.d(TAG,"owner name is set");
so that Activity has access to all the layout components. Thanks solved :)
You replaced the content view in the first activity with a layout that include the onClick attribute, but you have no public void toaster(View view) method there.
So, either don't use setContentView a second time, or implement that method on both Activities.
The recommended way to replace the view is Fragments, by the way
This is a wrong way to change the contents of your Activity, The main problem here is that you have onClick attribute set to "toaster", And you don't have a function called "toaster" in your FirstActivity.
Beside that, The MainScreen Activity in your code will never be used.
So, Your problem is that you set the FirstActivity contents to "activity_main_screen.xml", And FirstActivity doesn't have "toaster" method in it, When you change the context, the Activity will try to find toaster method and the app will crash because the method doesn't exist in FirstActivity.
You can solve this problem by making a method called "toaster" inside FirstActivity, But
This is a very bad practice, You can use Fragments instead, Or you can use Intent to move to another activity.
Some useful links about Fragments:
https://developer.android.com/guide/components/fragments.html
https://www.tutorialspoint.com/android/android_fragments.htm
https://examples.javacodegeeks.com/android/core/app/fragment/android-fragments-example/
Why should I use fragment in Android?

This is my Activity
RelativeLayout custom_RelativeLayout = (RelativeLayout)findViewById(R.id.actionbar_relativelayout);
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM );
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(false);
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setBackgroundDrawable(
getApplicationContext().getResources().getDrawable(
R.drawable.drawable_actionbar_back));
getSupportActionBar().setCustomView(R.layout.custom_actionbar);
I want to its occupy whole space of action bar but it does not occupy i also read many answers on stackoverflow but didn't work.
1) I want match parent space in action bar

If you want to get the height of native action bar then use ?android:attr/actionBarSize in XML.
Now your XML will look like:
