Layout weight on dynamically added RemoteViews

问题

Within my widget, i'm using the following to dynamically add items (R.layout.widget_item) to a LinearLayout defined within my main widget layout:

//--  Main widget layout
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_design);

//--  Add to main layout
RemoteViews newView = new RemoteViews(context.getPackageName(), R.layout.widget_item);
views.addView(R.id.view_container, newView);

My question is, how can I dynamically set the "android:layout_weight" attribute on the newView?

回答1:

See: http://developer.android.com/reference/android/widget/RemoteViews.html

newView in your example is an instance of class RemoteViews and I don't think you can easily set anything above and beyond what RemoteViews provides.

newView.setLayoutParams(layoutParams);

The above will not work because it's not part of RemoteViews.

As far as I can see... there may be some round about way of setting and finding dimensions and other layoutParams of RemoteViews, but I haven't found it yet.

回答2:

first you get the view params like this

layoutParams = newView.getParams();

then edit tham //layoutParams .setThis/setThat all kinds of manipulations you want to do

and then set the new params back to the view

newView.setLayoutParams(layoutParams);

回答3:

layout_weight is part of the LinearLayout.LayoutParams that you apply to a the LinearLayout, not the LinearLayout itself. There's a constructor that takes a third param representing the layout_weight.
