Вы можете использовать TextInputLayout и внутри, что вы можете определить Edit Text.
Я сделал некоторые изменения внутри вашего phone_dialog.xml.
phone_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_gravity="bottom"
android:background="@android:color/holo_blue_light"
android:padding="10dp"
app:behavior_hideable="true"
app:behavior_peekHeight="60dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/tvTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="8dp"
android:gravity="center"
android:padding="10dp"
android:text="dialog_title_edit_phone" />
<android.support.design.widget.TextInputLayout
android:id="@+id/inputPhone"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/TextInputLayoutLabel">
<EditText
android:id="@+id/etPhone"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter phone"
android:imeOptions="actionDone"
android:inputType="phone"
android:maxLines="1"
android:textSize="20sp" />
</android.support.design.widget.TextInputLayout>
<Button
android:id="@+id/btnSavePhone"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/etPhone"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="8dp"
android:text="Save" />
</LinearLayout>
</FrameLayout>
Внутри style.xml добавьте это.
<style name="TextInputLayoutLabel" parent="Widget.Design.TextInputLayout">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">@android:color/black</item>
<item name="android:textSize">15sp</item>
<!-- Label color in TRUE state and bar color FALSE and TRUE State -->
<item name="colorAccent">@color/colorPrimary</item>
<item name="colorControlNormal">@color/colorAccent</item>
<item name="colorControlActivated">@color/colorAccent</item>
</style>
PhoneBottomDialog.java
public class PhoneBottomDialog extends BottomSheetDialog {
TextInputLayout inputPhone;
EditText edtPhone;
Button btnSave;
public PhoneBottomDialog(Context context) {
super(context);
View view = getLayoutInflater().inflate(R.layout.phone_dialog, null);
setContentView(view);
// additional setup below this...
inputPhone = (TextInputLayout) view.findViewById(R.id.inputPhone);
edtPhone = (EditText) view.findViewById(R.id.etPhone);
btnSave = (Button) view.findViewById(R.id.btnSavePhone);
btnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!validatePhone())
return;
}
});
}
private boolean validatePhone() {
if (edtPhone.getText().toString().isEmpty()) {
inputPhone.setError("Please enter valid phone number with country code.");
requestFocus(edtPhone);
return false;
} else {
inputPhone.setErrorEnabled(false);
}
return true;
}
private void requestFocus(View view) {
if (view.requestFocus()) {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}
// ...
}
И внутри Activity.
@SuppressLint("SetTextI18n")
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test24);
mContext = this;
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
PhoneBottomDialog dialog = new PhoneBottomDialog(mContext);
dialog.show();
}
Ниже вы можете увидеть результат для этого.
