关键代码：
1.在AndroidManifest.xml设置对应的Activity:
android:windowSoftInputMode="adjustResize"
2.activity对应的布局：

                int loc[] = new int[2];

                    view.setVisibility(View.VISIBLE);
                } else {
                    view.setVisibility(View.INVISIBLE);

另外，还可以自定义Layout通过onLayout()方法来实现、或可以在Activity内嵌DialogFragment,先记下，有空再写。
