Question

我使用下面的代码创建了一个Activity作为对话框，我将其放入清单中。但问题是它有标题栏，我该如何删除它？

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

Answer 1

使用此代码

final Dialog dialog = new Dialog(context);
    dialog.getWindow();
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);       
    dialog.setContentView(R.layout.yourlayout);
    dialog.show();

Answer 2

如果对话..............

Dailog dialog = new Dialog(MainActivity.this, R.style.mydialogstyle);

<强> RES - ＆GT;值 - ＆GT; mydialog.xml

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

Answer 3

对于我的工作：

<style name="MyActivityDialogTheme" parent="Base.Theme.AppCompat.Light.Dialog">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowActionBar">false</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

Answer 4

创建对话框时使用此代码：

requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 5

对于使用AppCompatActivity的用户，以上答案可能无效。

尝试一下

=SUM(SPLIT(A1,":"))

Answer 6

这对我有用

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

和这个

requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 7

从活动中移除标题栏，使用对话框主题 ActionBarActivity 或 AppcompatActivity

<style name="Theme.MyDialog" parent="@style/Theme.AppCompat.Light.Dialog">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Answer 8

它对我有用：

在我的自定义对话框活动的onCreate（）中：

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

    //your code....

}

清单：

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

样式：

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

Handler _alerthandler = new Handler();
    Runnable _alertrunnable = new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            ProfileActivity.this.runOnUiThread(new Runnable() {
                public void run() {
                    // Create custom dialog object
                    final Dialog dialog = new Dialog(ProfileActivity.this);
                    // Include dialog.xml file
                    dialog.getWindow();
                    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                    dialog.setContentView(R.layout.alertbox);
                    TextView title = (TextView) dialog
                            .findViewById(R.id.AlertBox_Title);
                    title.setText(Appconstant.Toast_Title);
                    TextView text = (TextView) dialog
                            .findViewById(R.id.AlertBox_Msg);
                    text.setText(Appconstant.Toast_Msg);
                    dialog.show();

                    Button declineButton = (Button) dialog
                            .findViewById(R.id.AlertBox_Ok);
                    // if decline button is clicked, close the custom dialog
                    declineButton.setOnClickListener(new OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            // Close dialog
                            dialog.dismiss();
                        }
                    });
                }
            });
        }
    };
