android Kitkat 4.4 上的自定义对话框切割顶部区域

Question

在我的 android 应用程序中，我在我的 activity 中使用 custom dialog。我为这个自定义对话框赋予了透明背景的样式。我在 Kitkat 4.4 上遇到了奇怪的问题。该对话框仅在 Kitkat 4.4 上从顶部切开。SDK 级别 this 链接，但没有得到如何按照我的要求实现它。 谢谢。

代码：

 public void showGameOverDialog(int score) {

        final Dialog dialog = new Dialog(Level1Activity_Room.this,
                R.style.DialogBackground);
        dialog.setContentView(R.layout.gameover_dialog_layout);         
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);
        dialog.show();
}

R.style.DialogBackground ：

 <style name="DialogBackground" parent="@android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

最后我通过对现有代码的一些修改解决了这个问题。还将目标级别从 Project->Right Click->Android 更改为 Android 4.4

    public void showGameOverDialog(int score) {
        final Dialog dialog = new customeDialogClass(Level1Activity_Room.this,
                R.style.DialogBackground);
        dialog.setContentView(R.layout.gameover_dialog_layout);
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);
dialog.show();
}

customeDialogClass.java

 @TargetApi(14)
public class customeDialogClass extends Dialog {

    public customeDialogClass(Context context) {
        super(context);
        if (Build.VERSION.SDK_INT < 18) {
            return;
        }

        // The UI options currently enabled are represented by a bitfield.
        // getSystemUiVisibility() gives us that bitfield.
        int uiOptions = getWindow().getDecorView().getSystemUiVisibility();
        int newUiOptions = uiOptions;
        boolean isImmersiveModeEnabled = ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);
        if (isImmersiveModeEnabled) {
            Log.e("log1---", "Turning immersive mode mode off.");
        } else {
            Log.e("log2-----", "Turning immersive mode mode on.");
        }

        // Status bar hiding: Backwards compatible to Jellybean
        if (Build.VERSION.SDK_INT >= 16
                && (newUiOptions & View.SYSTEM_UI_FLAG_FULLSCREEN) <= 0) {
            newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;
        }

        if (Build.VERSION.SDK_INT >= 18
                && (newUiOptions & View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) <= 0) {
            newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        }

        getWindow().getDecorView().setSystemUiVisibility(newUiOptions);
    }

    public customeDialogClass(Context context, boolean cancelable,
            OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
    }

    public customeDialogClass(Context context, int theme) {
        super(context, theme);
        if (Build.VERSION.SDK_INT < 18) {
            return;
        }

        // The UI options currently enabled are represented by a bitfield.
        // getSystemUiVisibility() gives us that bitfield.
        int uiOptions = getWindow().getDecorView().getSystemUiVisibility();
        int newUiOptions = uiOptions;
        boolean isImmersiveModeEnabled = ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);
        if (isImmersiveModeEnabled) {
            Log.e("log1---", "Turning immersive mode mode off.");
        } else {
            Log.e("log2-----", "Turning immersive mode mode on.");
        }

        // Status bar hiding: Backwards compatible to Jellybean
        if (Build.VERSION.SDK_INT >= 16
                && (newUiOptions & View.SYSTEM_UI_FLAG_FULLSCREEN) <= 0) {
            newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;
        }

        if (Build.VERSION.SDK_INT >= 18
                && (newUiOptions & View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) <= 0) {
            newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        }
        getWindow().getDecorView().setSystemUiVisibility(newUiOptions);
    }

}

kitkat 4.4 中没有问题，我认为问题出在 R.layout.gameover_dialog_layout 中以获得屏幕支持

Answer 3

它通常通过在 Android 4.4 或更低版本中添加的标题栏。 通过在自定义对话框中添加以下行来解决此问题。

dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
