Android 软键盘导致UI被遮挡问题
情况1：LinearLayout+android:fitsSystemWindows="false"(根目录) +android:windowSoftInputMode="stateHidden|adjustResize"(mainfast)
// 上面设置情况 软键盘弹出页面不会动 自己来监听软键盘高度 然后设置父布局的paddingBottom为软键盘高度
KeybordS.observeSoftKeyboard(getWContext().get(), new KeybordS.OnSoftKeyboardChangeListener() {
@Override
public void onSoftKeyBoardChange(int softKeybardHeight, boolean visible) {
if (!visible) softKeybardHeightInClose = softKeybardHeight;
JLog.e(visible + "--" + softKeybardHeight);
if (visible) {
llMall.setPadding(0, 0, 0, softKeybardHeight - softKeybardHeightInClose);
} else {
llMall.setPadding(0, 0, 0, 0);
}
}
});
情况二：android:fitsSystemWindows="true" +android:windowSoftInputMode="stateHidden|adjustResize"+ScrollView
并且外部套有一层ScrollView
// 上面设置情况 软键盘弹出页面会进行绘制下方自己加上一个边距 让原来最下面的控件露出来
但是因为fitsSystemWindows=true 重新绘制 然后被滚动到了焦点位置 所以焦点下方的控件又被遮挡了
//所以我们直接滚动打最底部就可以
// 输入框UI重新计算可视区域 方便把发布按钮顶上去
KeybordS.observeSoftKeyboard(this, new KeybordS.OnSoftKeyboardChangeListener() {
@Override
public void onSoftKeyBoardChange(int softKeybardHeight, boolean visible) {
if (visible) {
scrollview.smoothScrollTo(0, scrollview.getChildAt(0).getHeight());
} else {

}
}
