Android Dialog: Removing title bar

问题:

I have a weird behavior I can't pinpoint the source of.

I have my app with the classic

requestWindowFeature(Window.FEATURE_NO_TITLE);

to remove the title/status bar.

I then create a Dialog box to allow the user to enter information (name etc)

With a physical keyboard, no problem but when I use the virtual keyboard I have a strange behavior:

each time I hit a key on the virtual key board the title/status bar reappears pushing all the keyboard layout around then vanishes again (just like the animation of when I start the application)

here is some code :

        dialog = new Dialog(context);
        dialog.setContentView(R.layout.logindialog);
        dialog.setTitle("Login:");

        WindowManager.LayoutParams a = dialog.getWindow().getAttributes();

//      dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

        a.dimAmount = 0;
        dialog.getWindow().setAttributes(a);

        dialog.setCancelable(true);
        dialog.getWindow().setLayout(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);

and then

dialog.show();

I tried

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

but it crashes my app.

here is the xml

    <TextView android:id="@+id/LoginText"
        android:gravity="fill"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Login:">
    </TextView>         
    <EditText android:id="@+id/LoginEdit"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:text="jason"
        android:layout_width="200sp"/>
    <TextView android:id="@+id/PasswordText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Password:">
    </TextView>         
    <EditText android:id="@+id/PasswordEdit"
        android:layout_height="wrap_content"
        android:singleLine="true"
        android:text="welcome"
        android:layout_width="200sp"
        android:password="true"/>
<LinearLayout 
    android:id="@+id/test2"
    android:gravity="center_horizontal"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
<Button android:id="@+id/LoginButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Login" />
<Button android:id="@+id/CreateButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Create" />
<Button android:id="@+id/CancelLogin"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="Cancel" />
</LinearLayout>/>

回答1:

use,

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

回答2:

create new style in styles.xml

<style name="myDialog" parent="android:style/Theme.Dialog">
   <item name="android:windowNoTitle">true</item>
</style>

then add this to your manifest:

 <activity android:name=".youractivity" android:theme="@style/myDialog"></activity>

回答3:

All the above answer not working for me for AppCompatDialog

If you are using AppCompatDialog try this

Important note: Set this before calling setContentView.

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);

回答4:

create your XML which is shown in dialog here it is activity_no_title_dialog

final Dialog dialog1 = new Dialog(context);
dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog1.setContentView(R.layout.activity_no_title_dialog);
dialog1.show();

回答5:

You can also define Theme in android manifest file for not display Title bar..

You just define theme android:theme="@android:style/Theme.Light.NoTitleBar" in activity where u dont want to display title bar

Example:-

    <uses-sdk android:minSdkVersion="4"android:targetSdkVersion="4" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".splash"
              android:label="@string/app_name" android:screenOrientation="portrait"
              android:theme="@android:style/Theme.Light.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<activity android:name="main" android:screenOrientation="portrait" android:theme="@android:style/Theme.Light.NoTitleBar"></activity>

回答6:

if you are using a custom view then remeber to request window feature before adding content view like this

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
dialog.show();

回答7:

use below code before setcontentview :-

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.custom_dialog);

Note:- above code must have to use above dialog.setContentView(R.layout.custom_dialog);

In XML use a theme

android:theme="@android:style/Theme.NoTitleBar"

also styles.xml:

<style name="hidetitle" parent="android:style/Theme.Dialog">
   <item name="android:windowNoTitle">true</item>
</style>

And then:

Dialog dialog_hidetitle_example = new Dialog(context, R.style.hidetitle);

回答8:

I am an Android novice and came across this question trying to get rid of a title bar.

I'm using an activity and displaying it as a dialog. I was poking around with themes and came across a useful bit of default theming.

Here's the code from my AndroidManifest.xml that I was using when the title bar was showing:

<activity
    android:name=".AlertDialog"
    android:theme="@android:style/Theme.Holo.Dialog"

    >

</activity>

Here's the change that got me my desired result:

<activity
    android:name=".AlertDialog"
    android:theme="@android:style/Theme.Holo.Dialog.NoActionBar"

    >

</activity>

As I said, I'm still new to Android, so this may have undesirable side-effects, but it appears to have given me the outcome I wanted, which was just to remove the title bar from the dialog.

I'm using next variant:

Activity of my custom Dialog:

public class AlertDialogue extends AppCompatActivity {

    Button btnOk;
    TextView textDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_alert_dialogue);

        textDialog = (TextView)findViewById(R.id.text_dialog) ;
        textDialog.setText("Hello, I'm the dialog text!");

        btnOk = (Button) findViewById(R.id.button_dialog);
        btnOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
    }
}

activity_alert_dialogue.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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:layout_width="300dp"
    android:layout_height="wrap_content"
    tools:context=".AlertDialogue">

    <TextView
        android:id="@+id/text_dialog"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="24dp"
        android:text="Hello, I'm the dialog text!"
        android:textColor="@android:color/darker_gray"
        android:textSize="16dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <Button
        android:id="@+id/button_dialog"
        android:layout_width="wrap_content"
        android:layout_height="36dp"
        android:layout_margin="8dp"
        android:background="@android:color/transparent"
        android:text="Ok"
        android:textColor="@android:color/black"
        android:textSize="14dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/text_dialog" />


</android.support.constraint.ConstraintLayout>

Manifest:

<activity android:name=".AlertDialogue"
            android:theme="@style/AlertDialogNoTitle">
</activity>

Style:

<style name="AlertDialogNoTitle" parent="Theme.AppCompat.Light.Dialog">
        <item name="android:windowNoTitle">true</item>
</style>

回答10:

With next variant I have no reaction:

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

So, I try to use next:

dialog.supportRequestWindowFeature(Window.FEATURE_NO_TITLE); //before     
dialog.setContentView(R.layout.logindialog);

This variant work excellent.

回答11:

This worked for me.

Dailog dialog = new Dialog(MyActivity.this, R.style.dialogstyle);

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="dialogstyle" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@null</item>
        <item name="android:windowNoTitle">false</item>
    </style>
</resources>

You can try this simple android dialog popup library. It is very simple to use on your activity.

When submit button is clicked try following code after including above lib in your code

Pop.on(this)
   .with()
   .title(R.string.title) //ignore if not needed
   .icon(R.drawable.icon) //ignore if not needed
   .cancelable(false) //ignore if not needed
   .layout(R.layout.custom_pop)
   .when(new Pop.Yah() {
       @Override
       public void clicked(DialogInterface dialog, View view) {
           Toast.makeText(getBaseContext(), "Yah button clicked", Toast.LENGTH_LONG).show();
       }
   }).show();

Add one line in your gradle and you good to go

dependencies {
    compile 'com.vistrav:pop:2.0'
}

回答13:

**write this before adding view to dialog.**

dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
