找了很久才找到一个合适的解决方案, 于是怒赞了一波原作者, 并且为本博客又摘录(抄?)了一篇优秀的博客回来. 啊哈哈…
因为我的需求是在 Fragment 中使用这种效果, 所以代码与原作者代码有些区别. mActivity 来自当前 Fragment.getActivity(), 新手请知悉.
先在清单文件中为该页面的activity加入这个属性:
android:windowSoftInputMode="adjustPan|stateHidden"
下面贴下代码 :
View decorView = mActivity.getWindow().getDecorView();
View contentView = mActivity.findViewById(Window.ID_ANDROID_CONTENT);
decorView.getViewTreeObserver().addOnGlobalLayoutListener(getGlobalLayoutListener(decorView, contentView));
private ViewTreeObserver.OnGlobalLayoutListener getGlobalLayoutListener(final View decorView, final View contentView) {
return new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
decorView.getWindowVisibleDisplayFrame(r);
int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
int diff = height - r.bottom;
if (diff != 0) {
if (contentView.getPaddingBottom() != diff) {
contentView.setPadding(0, 0, 0, diff);
}
} else {
if (contentView.getPaddingBottom() != 0) {
contentView.setPadding(0, 0, 0, 0);
}
}
}
};
}
