SearchView是Android原生的控件,功能较全,简单修改代码可实现自定义的效果。

首先初始化一下控件

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

1, searchView有个默认“关闭”状态,点击一下放大镜🔍图标可以展开。如果想直接显示这个展示状态,可以这样写:(我就不上gif了,懒……)

mSearchView.setIconifiedByDefault(false);

2, 搜索文字下方有个下划线,如果想去掉下划线,可以把下划线的颜色改成与背景颜色一致,这样就能出来取消下划线的状态了。

其中R.id.search_plate是searchView源码中下划线的id,所以必须写正确了

View underline =mSearchView.findViewById(R.id.search_plate);

underline.setBackgroundColor(ContextCompat.getColor(this,R.color.white));

3, SearchView前面有一个默认自带的放大镜图标,如图,

f1fe616d630d

就是这个放大镜图标

如果想取消,可以这么写:

ImageView searchViewIcon = (ImageView)mSearchView.findViewById(R.id.search_mag_icon);

ViewGroup linearLayoutSearchView =(ViewGroup) searchViewIcon.getParent();

linearLayoutSearchView.removeView(searchViewIcon);

4,修改键入的文字字体大小、颜色和hint的字体颜色

final EditText editText = (EditText)mSearchView.findViewById(R.id.search_src_text);

editText.setTextSize(TypedValue.COMPLEX_UNIT_PX,getResources()

.getDimension(R.dimen.np_search_text_size));

editText.setTextColor(ContextCompat.getColor(this,R.color.nb_text_primary));

editText.setHintTextColor(ContextCompat.getColor(this,R.color.nb_text_quaternary));

5,当点击软键盘上的”搜索“的时候,自动触发对已经输入文字的搜索:

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {

@Override

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

if (actionId == EditorInfo.IME_ACTION_SEARCH) {

//搜索逻辑

}

return true;

}

});

6,自定义searchView布局最右侧”❌“号图标:

ImageView closeViewIcon = (ImageView)mSearchView.findViewById(R.id.search_close_btn);

closeViewIcon.setImageDrawable(ContextCompat

.getDrawable(this,R.drawable.ic_search_close));```

7,自定义光标颜色:

try {

Field fCursorDrawableRes = TextView.class

.getDeclaredField("mCursorDrawableRes");

fCursorDrawableRes.setAccessible(true);

//此处的editText是上文第4条中的editText

int mCursorDrawableRes = fCursorDrawableRes.getInt(editText);

Field fEditor = TextView.class.getDeclaredField("mEditor");

fEditor.setAccessible(true);

//此处的editText是上文第4条中的editText

Object editor = fEditor.get(editText);

Class> clazz = editor.getClass();

Field fCursorDrawable =

clazz.getDeclaredField("mCursorDrawable");

fCursorDrawable.setAccessible(true);

if (mCursorDrawableRes <= 0) {

return;

}

Drawable cursorDrawable =

ContextCompat.getDrawable(mSearchView.getContext(), mCursorDrawableRes);

if (cursorDrawable == null) {

return;

}

Drawable tintDrawable = DrawableCompat.wrap(cursorDrawable);

DrawableCompat.setTintList(tintDrawable,

//此处的R.color.blue_primary就是你自定义的颜色了

ColorStateList.valueOf(

ContextCompat.getColor(this, R.color.blue_primary)));

Drawable[] drawables

= new Drawable[] {tintDrawable, tintDrawable};

fCursorDrawable.set(editor, drawables);

} catch (Throwable ignored) {

}

还有一些自定义的功能,网上一搜一堆,我就不在这里列举了~~
