Android 点击键盘外的区域收起键盘

拷贝入BaseActivity 或 具体Activity

Java实现：

/**
     * 点击非编辑区域收起键盘
     * 获取点击事件
     * CSDN-深海呐
     */
    @CallSuper
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() ==  MotionEvent.ACTION_DOWN ) {
            View view = getCurrentFocus();
            if (KeyboardsUtils.isShouldHideKeyBord(view, ev)) {
                KeyboardsUtils.hintKeyBoards(view);
            }
        }
        return super.dispatchTouchEvent(ev);
    }
           

Kotlin实现：

/**
     * 点击非编辑区域收起键盘
     * 获取点击事件
     * CSDN-深海呐
     */
    @CallSuper
    override fun dispatchTouchEvent(ev: MotionEvent): Boolean {
        if (ev.action == MotionEvent.ACTION_DOWN) {
            val view = currentFocus
            if (KeyboardsUtils.isShouldHideKeyBord(view, ev)) {
                KeyboardsUtils.hintKeyBoards(view)
            }
        }
        return super.dispatchTouchEvent(ev)
    }
           

KeyboardsUtils：

public class KeyboardsUtils {

    /**
     * 显示软键盘
     * @param view
     */
    public static void showKeyboard(View view) {
        InputMethodManager imm = (InputMethodManager) view.getContext()
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            view.requestFocus();
            imm.showSoftInput(view, 0);
        }
    }

    /**
     * 隐藏软键盘
     * @param view
     */
    public static void hintKeyBoards(View view) {
        InputMethodManager manager = ((InputMethodManager) view.getContext()
                .getSystemService(Context.INPUT_METHOD_SERVICE));
        if (manager != null) {
            manager.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
    }

    /**
     * 判定当前是否需要隐藏
     */
    public static boolean isShouldHideKeyBord(View v, MotionEvent ev) {
        if (v != null && (v instanceof EditText)) {
            int[] l = {0, 0};
            v.getLocationInWindow(l);
            int left = l[0];
            int top = l[1];
            int bottom = top + v.getHeight();
            int right = left + v.getWidth();
            return !(ev.getX() > left && ev.getX() < right && ev.getY() > top && ev.getY() < bottom);
        }
        return false;
    }
}
