Java Android对话框片段自动调整大小

我的问题类似于，但那个问题并不能完全解决我的问题

我有一个

DialogFragment

，我想为它设置最大尺寸，如果DialogFragment超出了显示边界，它会自动调整大小。这似乎是应该放在操作系统中的东西，但我能想到的唯一解决方案是轮询显示维度，并在维度超出显示边界时手动调整大小

在

对话框fragment

的

onCreateView（布局充气机、视图组容器、捆绑包保存状态）

：

在

Globals.java

中调整代码大小：

// Adjusts the size of a dialog fragment's popup view to ensure that it fits within the display of the current device
public static void AdjustSizeOfDialogFragment(final Activity parentActivity, final View popupRoot)
{
    // If all of our function parameters are valid
    if ((parentActivity != null) && (popupRoot != null))
    {
        // If the dialog's root view has already rendered (has defined layout parameters)
        if (popupRoot.getLayoutParams() != null)
        {
            // Resize the dialog now
            ResizeDialogFragment(parentActivity, popupRoot);
        }
        // Else the view has not finished rendering yet
        else
        {
            // Assign a listener to notify us when it has finished rendering
            popupRoot.addOnLayoutChangeListener(new OnLayoutChangeListener()
            {
                public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom)
                {
                    // Remove the layout listener
                    v.removeOnLayoutChangeListener(this);

                    // Now we can render the dialog
                    ResizeDialogFragment(parentActivity, popupRoot);
                }
            });
        }
    }
}

// Does the actual logic/math behind the AdjustSizeOfDialogFragment function
private static void ResizeDialogFragment(Activity parentActivity, View popupRoot)
{
    // Retrieves information about the display of the current device
    DisplayMetrics              deviceDisplayMetrics    = new DisplayMetrics();
    // Layout parameters that need to be applied to the popup's root view
    LinearLayout.LayoutParams   llParams                = null;
    FrameLayout.LayoutParams    flParams                = null;

    // If all of our function parameters are valid
    if ((parentActivity != null) && (popupRoot != null) && (popupRoot.getLayoutParams() != null))
    {
        // Retrieve the layout parameters from the popup's root view and also get information on the current device's display
        if (popupRoot.getLayoutParams() instanceof LinearLayout.LayoutParams)
        {
            llParams = (LinearLayout.LayoutParams) popupRoot.getLayoutParams();
        }
        else if (popupRoot.getLayoutParams() instanceof FrameLayout.LayoutParams)
        {
            flParams = (FrameLayout.LayoutParams) popupRoot.getLayoutParams();
        }
        parentActivity.getWindowManager().getDefaultDisplay().getMetrics(deviceDisplayMetrics);

        // If either the height or width of the popup view is greater then the height or width
        // of the current display, clip them to approximately 90% of the display's width/height.
        if (llParams != null)
        {
            if (llParams.width > deviceDisplayMetrics.widthPixels)
            {
                llParams.width = (int) (deviceDisplayMetrics.widthPixels * 0.9);
            }
            if (llParams.height > deviceDisplayMetrics.heightPixels)
            {
                llParams.height = (int) (deviceDisplayMetrics.heightPixels * 0.9);
            }
        }
        else if (flParams != null)
        {
            if (flParams.width > deviceDisplayMetrics.widthPixels)
            {
                flParams.width = (int) (deviceDisplayMetrics.widthPixels * 0.9);
            }
            if (flParams.height > deviceDisplayMetrics.heightPixels)
            {
                flParams.height = (int) (deviceDisplayMetrics.heightPixels * 0.9);
            }
        }
    }
}

问题是：真正的Android方式是什么？这是我唯一的选择吗？这似乎是应该内置到操作系统中的东西，但我问过的人都找不到它。

可能是因为windows正在调整DialogFragment的显示，因此，如果将所显示活动的

AndroidManifest.xml

中的

windowSoftInputMode

属性设置为

adjustNothing

，则可以解决问题

<activity
    ...
    android:windowSoftInputMode="adjustNothing">
...

<activity
    ...
    android:windowSoftInputMode="adjustNothing">
...
