Sim*_* L. 7 android android-layout window-soft-input-mode android-coordinatorlayout
我在我的Android应用程序中有以下布局但我windowSoftInputMode="adjustResize"在活动中遇到问题:名为"容器"的LinearLayout包含多个EditTexts但当其中一个有焦点并且键盘出现时,Activity不会调整大小并且EditText隐藏在键盘后面.我认为这与它有关,CoordinatorLayout但我无法弄清楚它有什么问题.

我已经尝试过Coordinatorlayout adjustresize不工作,我使用支持库23.1.1(不像CoordinatorLayout和NestedScrollView一样不调整adjustResize)
这是另一个答案.为我工作完美.

public KeyboardUtil(Activity act, View contentView) {
this.decorView = act.getWindow().getDecorView();
this.contentView = contentView;
//only required on newer android versions. it was working on API level 19
if (Build.VERSION.SDK_INT >= 19) {

}
}
public void disable() {
if (Build.VERSION.SDK_INT >= 19) {
decorView.getViewTreeObserver().removeOnGlobalLayoutListener(onGlobalLayoutListener);
}
}
//a small helper to allow showing the editText focus
ViewTreeObserver.OnGlobalLayoutListener onGlobalLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
//r will be populated with the coordinates of your view that area still visible.
decorView.getWindowVisibleDisplayFrame(r);
//get screen height and calculate the difference with the useable area from the r
int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
int diff = height - r.bottom;
//if it could be a keyboard add the padding to the view
if (diff != 0) {
// if the use-able screen height differs from the total screen height we assume that it shows a keyboard now
//check if the padding is 0 (if yes set the padding for the keyboard)
if (contentView.getPaddingBottom() != diff) {
//set the padding of the contentView for the keyboard
contentView.setPadding(0, 0, 0, diff);
}
} else {
//check if the padding is != 0 (if yes reset the padding)
if (contentView.getPaddingBottom() != 0) {
//reset the padding of the contentView
contentView.setPadding(0, 0, 0, 0);

然后,您可以通过执行以下操作在活动中使用它:
//初始化KeyboardUtil(你可以做全局)
KeyboardUtil keyboardUtil = new KeyboardUtil(this, findViewById(android.R.id.content));
//enable it
keyboardUtil.enable();

要禁用此调整大小,请执行此操作
//disable it
keyboardUtil.disable();
