Why android is configured in full screen mode

Question

I'm trying to create my own dialogue

Basic layout (I also tried various modified layouts)

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:background="@color/dialogHeaderBackground"
            android:gravity="center"
            android:minHeight="@dimen/minHeightDialogTitle"
            android:text=""
            android:textStyle="bold" />

        <TextView
            android:id="@+id/message"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_below="@+id/title"
            android:layout_marginTop="5dp"
            android:text="" />

        <LinearLayout
            android:id="@+id/loutButton"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_below="@+id/message"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="5dp"
            android:orientation="horizontal" >

            <Button
                android:id="@+id/btnNeutral"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="" />

            <Button
                android:id="@+id/btnNegative"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="" />

            <Button
                android:id="@+id/btnPositive"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="" />
        </LinearLayout>
    </RelativeLayout>

Java code

        Dialog dialog = new Dialog(this);
//      Dialog dialog = new Dialog(this,R.style.Theme_Dialog);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        dialog.setContentView(R.layout.custom_dialog);

        Button btnPositive=(Button) dialog.findViewById(R.id.btnPositive);
        Button btnNegative=(Button) dialog.findViewById(R.id.btnNegative);
        Button btnNeutral=(Button) dialog.findViewById(R.id.btnNeutral);

        TextView txvTitle=(TextView)dialog.findViewById(R.id.title);
        TextView txvMessage=(TextView)dialog.findViewById(R.id.message);
        ...
        so on and so forth

I get the following dialog, which is fullscreen, WHICH I NOT HANT

Solutions already tried that give the same results as the previous screenshot

• Configuration Styles.xml 1 | Implemented Pastebin code
• Configuration Styles.xml 2 | Implemented Pastebin code
• An example presented in the Android Dev Guide using AlertDialog.Builder | Java code implemented
• None of my base layouts use MATCH_PARENTheight. As said in this stack overflow answer
• WRAP_CONTENT , | Java Pastebin
• RelativeLayout LinearLayout, . 3- answer

Answer 3

Ya, . google docs .

, RelativeLayout . , RelativeLayout, ​​ WRAP_CONTENT child ALIGN_PARENT_BOTTOM

, linearlayout . .

,

java- , , . ,

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int width = metrics.widthPixels; 

@guobao

DisplayMetrics displayMetrics = new DisplayMetrics();
dialog.getWindow().getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = (new width);
params.height = (new height);

ask me if any additional specification is needed.

Answer 4

you can set this code in your dialog box

DisplayMetrics displayMetrics = new DisplayMetrics();
dialog.getWindow().getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
params.width = (the width you want to set);
params.height = (the height you want to set);

Answer 5

That was my approach when I ran into the same problem.

I extended DialogFragment (from support.v4 lib)

And then inflate:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();
    final View view = inflater.inflate(R.layout.dialog_whatever, null);

    builder.setView(view);
    return builder.create();
}

This is the layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/rounded_corners"
    android:padding="20dp">

    <TextView
        android:id="@+id/confirm_dialog_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:textColor="@color/black"
        android:text="@string/are_you_sure_declining_whatever"/>

    <LinearLayout
        android:layout_marginTop="20dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|bottom"
        android:orientation="horizontal">

        <Button
            android:id="@+id/cancel_action"
            android:layout_marginRight="10dp"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@color/transparent"
            android:text="@string/cancel"
            android:textColor="@color/accent_color"/>

        <Button
            android:id="@+id/confirm_action"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@color/transparent"
            android:textColor="@color/accent_color"
            android:text="@string/reject"/>

    </LinearLayout>
</LinearLayout>

This approach also follows material development guidelines!

Hope this helps you.

Yours faithfully,
