android – adjustResize不适用于CoordinatorLayout

我的 Android应用程序中有以下布局,但我在活动中遇到windowSoftInputMode =“adjustResize”的问题：
名为“container”的LinearLayout包含多个EditTexts,但当其中一个具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CoordinatorLayout有关,但我无法弄清楚它有什么问题.

我已经尝试过Coordinatorlayout adjustresize not working并使用支持库23.1.1(不像CoordinatorLayout with NestedScrollView doesn’t resize with adjustResize)

解决方法

这是另一个 answer.
为我工作完美.

import android.app.Activity;
import android.graphics.Rect;
import android.os.Build;
import android.view.View;
import android.view.ViewTreeObserver;
import android.view.inputmethod.InputMethodManager;

public class KeyboardUtil {
    private View decorView;
    private View contentView;

    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) {
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
        }
    }

    public void enable() {
        if (Build.VERSION.SDK_INT >= 19) {
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
        }
    }

    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,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);
                }
            }
        }
    };


    /**
     * Helper to hide the keyboard
     *
     * @param act
     */
    public static void hideKeyboard(Activity act) {
        if (act != null && act.getCurrentFocus() != null) {
            InputMethodManager inputMethodManager = (InputMethodManager) act.getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(act.getCurrentFocus().getWindowToken(),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();
