how can i make my app compatible with all screen sizes without making different layout files for it?

I have a linear layout for buttons so when i run the app on different mobiles some of the buttons get hidden. As my app is ready in terms of code so i want some short technique to make it compatible for all screen sizes.

Percent Relative Layout
https://developer.android.com/reference/android/support/percent/PercentRelativeLayout.html
Constraint Layout
https://developer.android.com/training/constraint-layout/index.html

Use layout_weight. Research about them. I have started using layout_weight and they adjust to any screen size. Weights are used in LinearLayouts and TableLayouts. There may be more but those are the two i have used them in. If you want space in between items, go to the layout text screen and type
<View
and press enter. it should guide you from there. Views also can have weight too.

do not give any fix size to button or TextView
as per above code you give
<ImageView
android:id="#+id/about_btn"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="#drawable/about"
android:layout_gravity="center"
android:elevation="4dp"/>``
Imageview you give fix size 50dp for(height and width).Image view Hight&Width never change when you run different mobile phone.
so most of use Wrap_content and Match_Parent

Android: OnClick method for Button doesn't respond

I have set for every linear layout visibility when one button which is working is clicked to visible, so i think that is not the problem.
This is the code in java:
if (getMovieCategory.equals("movies")) {
buttonCategoryMovie.setText("MOVIES");
buttonCategoryMovie.setTextColor(Color.parseColor("#ffffff"));
buttonCategoryMovie.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_cancelar, 0, 0, 0);
buttonCategoryMovie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String movies = "movies";
dbh.updateCategoryMovies(birthdayId, movies);
}
});
} else {
buttonCategoryMovie.setText("MOVIES");
buttonCategoryMovie.setTextColor(Color.parseColor("#ffffff"));
buttonCategoryMovie.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_add, 0, 0, 0);
buttonCategoryMovie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dbh.deleteMovies(getMovieCategory);
}
});
}
Here everything is working except onClick. I'm getting no errors. My button doesn't respond on click.

try by handling setOnClickListener out side the if condition.

.You're coding with a lot of redundancy and risking introducing errors, some of which may not be immediately obvious. Here's a leaner and clearer version of your posted code sample, using one onClick method to handle your if(){else} conditions.
buttonCategoryMovie.setText("MOVIES");
buttonCategoryMovie.setTextColor(Color.parseColor("#ffffff"));
buttonCategoryMovie.setCompoundDrawablesWithIntrinsicBounds(
getMovieCategory.equals("movies") ? R.drawable.ic_cancelar : R.drawable.ic_add, 0,0,0
);
buttonCategoryMovie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (getMovieCategory.equals("movies")) {
String movies = "movies";
dbh.updateCategoryMovies(birthdayId, movies);
} else {
dbh.deleteMovies(getMovieCategory);
}
}
});
EDIT 1: I mistakenly left out your String movies = "movies" and have added it back in. If you're only going to use this String once, to pass it as a parameter for dbh.updateCategoryMovies(birthdayId, movies), then you could simply call dbh.updateCategoryMovies(birthdayId, "movies") and delete String movies = "movies"
EDIT 2: Without seeing your entire source code, I don't know if you're at all changing the value of getMovieCategory somewhere. If not, then the below sample will change it on every click of the button (once you launch the app to test the sample, your buttonCategoryMovie will be a generic Button; once you start clicking the button, it should toggle between showing your R.drawable.ic_cancelar and R.drawable.ic_add resources. If the button toggles between these two drawables, then you at least know that the button is in fact receiving the onClick.
Remember that, if the value of getMovieCategory doesn't change on each click, your button will always perform only one of the sets of onClick actions and it'll look like nothing's happening.
If it works for you as I've described, then you're on your way ;)
buttonCategoryMovie.setText("MOVIES");
buttonCategoryMovie.setTextColor(Color.parseColor("#ffffff"));
buttonCategoryMovie.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (getMovieCategory.equals("movies")) {
getMoviesCategory = "not movies"; // this is here just to test
buttonCategoryMovie.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_cancelar, 0, 0, 0);
String movies = "movies";
dbh.updateCategoryMovies(birthdayId, movies);
} else {
getMoviesCategory = "movies"; // this is here just to test
buttonCategoryMovie.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_add, 0, 0, 0);
dbh.deleteMovies(getMovieCategory);
}
}
});

Try changing android:visibility="gone" to android:visibility="visible" in your LinearLayout.
And again add android:clickable="true" to your LinearLayout

Clicking the button of the recyclerview item makes buttons of other recyclerview item respond too

I have created a recyclerview usin cardview and added button in each of the items of the recyclerview. I have already integrated the button click event . Now, when I click the button of one of the recyclerview item it responds normally and the button of other items responds too at the same time as if they are also clicked.what is the problem? how can it be solved?

Issue when using Scrollview inside Dialog

I am inflating a layout inside a dialog, which consist of a scrollview but the layout is not scrolling. I have referred so many questions from stackoverflow but then also its not working. My layout.xml is given below:
<?xml version="1.0" encoding="utf-8"?>

Dialog code
public void show_Alert_version_custom(String str, final String url,
final String exitStatus)// use for
{
final Dialog dialog = new Dialog(Splash.this);
dialog.setContentView(R.layout.version_update);
dialog.setTitle(getString(R.string.alert_title));
Button dialogButton2 = (Button) dialog.findViewById(R.id.btn_remind);
dialogButton = (Button) dialog.findViewById(R.id.btn_upgrade);
ImageView viewLine = (ImageView) dialog.findViewById(R.id.imageView2);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {}
});
// if button is clicked, close the custom dialog
dialogButton2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {}
});
dialog.show();
}

android:fillViewport="true" in ScrollView solved my problem. Now its scrolling even inside dialog.

You can use simply below code on ScollView. it's working fine.
<ScrollView>
<LinearLayout android:orientation="vertical"
android:scrollbars="vertical"
android:scrollbarAlwaysDrawVerticalTrack="true">
</LinearLayout>
</ScrollView>

Android: views in container still clickable after container view set to View.GONE

I have a LinearLayout that is a view in a FrameLayout. This LinearLayout sits on top in the frame.
Within this LinearLayout, there are some TextViews that are clickable. When I set the LinearLayout to View.GONE, everything goes away as expected except the TextViews are still clickable.
Why is this? And how do I avoid it other than setting all the clickable TextViews to View.GONE?

The fact that you change the visibility of a view doesn't mean that they are destroyed.
You should try adding something like this
yourButton.setClickable(false) ;
