java Android DialogFragment自动调整大小
我的问题类似于Full Screen DialogFragment in Android,但这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超出显示边界,它会自动调整大小。这似乎是应该在操作系统中烘焙的东西,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DialogFragment
的onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
中:
// Display the first screen
m_rootView = inflater.inflate(R.layout.fragment_popup, container, false);
// Readjust the size of the dialog fragment if it is too large for the display
Globals.AdjustSizeOfDialogFragment(getActivity(), container);
调整^{
// 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:真正的安卓方式是什么?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
# 1 楼答案
可能是因为windows正在调整DialogFragment的显示,所以如果在显示的活动的
AndroidManifest.xml
中将windowSoftInputMode
属性设置为adjustNothing
,就可以解决问题仅供参考:https://developer.android.com/training/keyboard-input/visibility.html#ShowOnStart
