Android中的searchView去掉前面的搜索圈

1.声明：

private SearchView mSearchView;

2.初始化：

mSearchView = (SearchView) findViewById(R.id.searchCity_searchView);

3.在对searchView进行findViewById之后，加上如下代码：

int magId = getResources().getIdentifier("android:id/search_mag_icon",null, null);

ImageView magImage = (ImageView) mSearchView.findViewById(magId);

magImage.setLayoutParams(new LinearLayout.LayoutParams(0, 0));

运行不再显示搜索圈
