Android 点击EditText外部区域隐藏小键盘

1.显示与隐藏键盘的方法

/**
     * 显示键盘
     * @param edit 输入焦点
     */
    public void showInputKeyboad(final EditText edit) {
        edit.requestFocus();
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(0, InputMethodManager.SHOW_FORCED);

    }
    /**
     * 隐藏键盘
     */
    protected void hideInputKeyboad() {
        InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        View v = this.getCurrentFocus();
        if (null != v) {
            imm.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }

2.重写Activiity中的方法

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View v = getCurrentFocus();
            if (isSoftShowing() && isShouldHideInput(v, ev)) {
                hideInputKeyboad();
            }
        }
        return super.dispatchTouchEvent(ev);
    }

3.判断软键盘是否正在展示

private boolean isSoftShowing() {
        //获取当前屏幕内容的高度
        int screenHeight = getWindow().getDecorView().getHeight();
        //获取View可见区域的bottom
        Rect rect = new Rect();
        getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
        return screenHeight - rect.bottom != 0;
    }

4.是否需要隐藏键盘

public boolean isShouldHideInput(View v, MotionEvent event) {
        if (v != null && (v instanceof EditText)) {
            int[] leftTop = {0, 0};
            //获取输入框当前的location位置
            v.getLocationInWindow(leftTop);
            int left = leftTop[0];
            int top = leftTop[1];
            if (event.getY() > top) {
                // 点击的是输入框上方区域
                return false;
            } else {
                return true;
            }
        }
        return false;
    }
