How to align EditText hint and input with AlertDialog message?

In my Android app I have an AlertDialog with an EditText to input the name of the user. The AlertDialog contains a title and a message, and the EditText contains a hint. All are left aligned, which is good, but they are not aligned with each other.
Here is my current code for the AlertDialog:
final EditText nameText = new EditText(this);
nameText.setHint(dialogHint);
AlertDialog dialog = new AlertDialog.Builder(this)
.setTitle(dialogTitle)
.setMessage(dialogMessage)
.setView(nameText)
.setPositiveButton(textPositiveButton, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// Get name from player
String highScoreName = String.valueOf(nameText.getText());
// Do something with highScoreName
}
})
.setNegativeButton(textNegativeButton, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// Do nothing
}
})
.create();
dialog.show();
This is how it looks:
And this is how I want it to look:
Is there a way to achieve this? Searching for answers online only led me to questions about central aligning the AlertDialog message or aligning separate AlertDialog and EditText views. Any help is appreciated.

Well, technically, you can add margins to your EditText programmatically, for example, like described here. Note, that you can request layoutParams of your EditText only after dialog.show() method call. I highly don't recommend to follow this way and I'm not sure about its reliability.
So the best option, like was mentioned in the comments, is custom dialog with your own fully customisable layout.
Create layout file. For example, custom_dialog.xml. And create your dialog view.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Message" />
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Hint" />
</LinearLayout>
Then insert it in the dialog.
View customDialogView = getLayoutInflater().inflate(R.layout.custom_dialog, null);
EditText editText = customDialogView.findViewById(R.id.edit_text);
AlertDialog alertDialog = new AlertDialog.Builder(requireContext())
.setView(customDialogView)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
editText.getText();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// Do nothing
}
})
.create();
alertDialog.show();

How to set fontfamily in AlertDialog edittext?

I don't know how to set fontfamily for alertdialog editext.
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Project name");
LinearLayout linearLayout = new LinearLayout(MainActivity.this);
linearLayout.setOrientation(LinearLayout.VERTICAL);
linearLayout.setPadding(10, 10, 10, 10);
final EditText editText = new EditText(MainActivity.this);
editText.setHint("Enter your project name");//here how to change text fontfamily
linearLayout.addView(editText);
builder.setView(linearLayout);
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
final String text = editText.getText().toString();
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.create().show();
}
});
I tried with TypeFace but it's not working. if you help me then it would be great and great and i will give you one big upvote.

try to these two line and check it working or not.
Typeface typeface=Typeface.create("font-family",Typeface.BOLD_ITALIC);
editText.setTypeface(typeface);

Try using
editText.setTypeface(
Typeface.create("serif", Typeface.NORMAL)
);

Make custom layout file for the dialog
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter Project Name"
android:fontFamily="#fonts/myFont" />
</LinearLayout>

The exception is caused by this line:
final String Notes = txtNotes.getText().toString();
As described in the reason, the txtNotes member is null, which means that the binding did not work (probably the view with txtnotes id was not found).
From what I see, you call ButternKnife.bind() for the activity which has the activity_show_the_post layout as content view. But the view with txtnotes id is actually in the create_comment layout, of which ButterKnife knows nothing about, and doesn't even exist at that time. Thus, the binding fails, no reference to txtnotes is created and you later get a NPE.

You need to bind the views for create_comment.xml too
view = getLayoutInflater().inflate(R.layout.create_comment,null);
Butterknife.bind(view,this);
alert.setCancelable(false);
alert.setView(view);
final AlertDialog dialog = alert.create();

Do not show again checkbox on a DialogFragment

So the title explains it all. I have a dialogfragment that currently pops up and I want to add a do not show checkbox to it and then obviously implement that check and not show if it was checked. I know there is a .setSingleChoiceItems, but I am not entirely sure on what would be going in there as it isn't really an item I would add somewhere. But then again I could probably be wrong as I am just getting into Android development.
Dialogfragment java
public class WifivsDataDialog extends DialogFragment {
#
Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.dialog_box)
.setPositiveButton(R.string.WiFi, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// FIRE ZE MISSILES!
}
})
.setNegativeButton(R.string.Cell_Data, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
}
});
// Create the AlertDialog object and return it
return builder.create();
}
}
Here is the code calling it in my MainActivity.java
WifivsDataDialog myDiag = new WifivsDataDialog();
myDiag.show(getFragmentManager(), "dialog_layout");
myDiag.setCancelable(false);

The accepted answer works, but it doesn't look like the normal material design system dialog, which is what I wanted.
Here's an option using a custom view layout to hold just the text and checkbox (with padding that matches material design), and allow the AlertDialog to manage the buttons.
no_location_dialog.xml layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="24dp"
android:paddingRight="12dp">
<TextView
android:id="#+id/no_location_text"
style="?android:attr/textAppearance"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="14dp"
android:paddingBottom="6dp"
android:text="#string/main_nolocation"
android:textSize="16sp"
android:autoLink="all"
android:linksClickable="true"></TextView>
<CheckBox
android:id="#+id/location_never_ask_again"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/main_never_ask_again" />
</LinearLayout>
And the code for setting up the AlertDialog:
private Dialog createNoLocationDialog() {
View view = getActivity().getLayoutInflater().inflate(R.layout.no_location_dialog, null);
CheckBox neverShowDialog = (CheckBox) view.findViewById(R.id.location_never_ask_again);
neverShowDialog.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
// Save the preference
PreferenceUtils.saveBoolean(getString(R.string.preference_key_never_show_location_dialog), isChecked);
}
});
Drawable icon = getResources().getDrawable(android.R.drawable.ic_dialog_map);
DrawableCompat.setTint(icon, getResources().getColor(R.color.theme_primary));
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
.setTitle(R.string.main_nolocation_title)
.setIcon(icon)
.setCancelable(false)
.setView(view)
.setPositiveButton(R.string.rt_yes,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
startActivityForResult(
new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS),
REQUEST_NO_LOCATION);
}
}
)
.setNegativeButton(R.string.rt_no,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// Ok, I suppose we can just try looking from where we
// are.
mMapFragment.mController.onLocation();
}
}
);
return builder.create();
}
It looks like this:

The DialogFragment class
public class WifivsDataDialog extends DialogFragment implements View.OnClickListener {
private CheckBox checkBox;
private Button button1;
private Button button2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View mainView = inflater.inflate(R.layout.wifi_dialog, container);
checkBox = (CheckBox) mainView.findViewById(R.id.checkBox);
button1 = (Button) mainView.findViewById(R.id.button1);
button2 = (Button) mainView.findViewById(R.id.button2);
button1.setOnClickListener(this);
button2.setOnClickListener(this);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
// Store the isChecked to Preference here
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putBoolean("DONT_SHOW_DIALOG", isChecked);
editor.commit();
}
});
return mainView;
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.button1:
// Do wifi stuff here
break;
case R.id.button2:
// Do cellular stuff here
break;
}
}
}
The Layout xml wifi_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="20dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some information to be displayed to human"
android:id="#+id/textView" android:textSize="30dp"/>
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Do now show this dialog again."
android:id="#+id/checkBox"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:gravity="center">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="WiFi"
android:id="#+id/button1" android:layout_gravity="center_horizontal"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="CELL"
android:id="#+id/button2"/>
</LinearLayout>
</LinearLayout>
And on your Activity or where ever you display the dialog, check the preference set by user before displaying the dialog. Something like below.
SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
boolean dontShowDialog = sharedPref.getBoolean("DONT_SHOW_DIALOG", false);
if (!dontShowDialog) {
new WifivsDataDialog().show(getFragmentManager(), "WiFi");
}

How to dismiss an android pop up window using an okay button

I'm making an app for a school project and I'm stuck on one area.
I want to use an okay button to dismiss the pop up window.
If you have any suggestions or if there is a better way to implement popups please share them.
package xyz.ashraf.whoisdelasalle;
import android.app.Activity;
import android.os.Bundle;
import android.util.DisplayMetrics;
public class Pop extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popwindow);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
getWindow().setLayout((int)(width*.8),(int)(height*.5));
}
}
Java code^
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"

Thanks in advance!

Not sure if this would work, but you can try:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popwindow);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
getWindow().setLayout((int)(width*.8),(int)(height*.5));
Button okButton = (Button) findViewById(R.id.okButton_who);
okButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
Or else you could use Dialogs or DialogFragments as akadouri suggested.

It looks like you're looking for Dialogs or DialogFragments.

I guess you could use AlertDialog to do this.
AlertDialog.Builder builder = new AlertDialog.Builder(mActivity);
builder.setTitle(title); // If you want a header title
builder.setCancelable(false); // If you want to stop user dismissing with back button
builder.setMessage(message); // Message to user
//If you want custom layout (not needed)
LayoutInflater inflater = mActivity.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.pin_dialog, null);
builder.setView(dialogView)
builder.setPositiveButton(positiveLable, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Do something
}
});
builder.setNegativeButton(negativeLable, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//Do something, or remove if you dont want negative button
}
});
builder.show();
