AdjustResize不适用于CoordinatorLayout [英] adjustResize does not work with CoordinatorLayout

问题描述

我的android应用中具有以下布局，但活动中的windowSoftInputMode="adjustResize"有问题: 名为"container"的LinearLayout包含多个EditTexts，但是当其中一个具有焦点并出现键盘时，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，但是我无法弄清楚这是怎么回事.

I have the following layout in my android app but I have a problem with windowSoftInputMode="adjustResize" in the activity: The LinearLayout named "container" contains multiple EditTexts but when one of them has focus and the keyboard appears, the Activity does not resize and the EditText is hidden behind the keyboard. I think this has something to do with the CoordinatorLayout but I can't figure out what is wrong with it.

我已经尝试过 Coordinatorlayout Adjustresize不起作用，并且我使用了支持库23.1.1(不像带有NestedScrollView的CoordinatorLayout不会通过AdjustResize调整大小)

I already tried Coordinatorlayout adjustresize not working and I use support library 23.1.1 (not like CoordinatorLayout with NestedScrollView doesn't resize with adjustResize)

推荐答案

这来自另一个答案. 为我完美地工作.

This is from another answer. Worked perfectly for me.

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, 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);
                }
            }
        }
    };


    /**
     * 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:

You can then use it in your activity by doing the following:

///初始化KeyboardUtil(您可以全局执行此操作)

//initialize the KeyboardUtil (you can do this global)

KeyboardUtil keyboardUtil = new KeyboardUtil(this, findViewById(android.R.id.content));

//enable it
keyboardUtil.enable();

要禁用此大小调整，请执行此操作

To disable this resizing, do this

//disable it
keyboardUtil.disable();
