android自定义searchView圆角

问题描述 投票:5回答:3

我想用一个不在ActionBar中的SearchView创建一个Activity(事实上,我正在使用NoActionBar主题)。现在我希望这个SearchView有圆角(不是实际SearchView中的EditText,而是SearchView本身),

像这样:Mockup

我所能管理的就是:actual SearchView

有人会暗示我要改变什么吗?活动的XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="false">
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="150dp"
    android:background="@color/theBlue">

    <SearchView
        android:id="@+id/search_view"
        android:layout_width="1000dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="20dp"
        android:background="@drawable/bg_white_rounded"
        android:clickable="true"/>
</RelativeLayout>

drawable / bg_white_rounded.xml代码:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff"/>
<corners android:radius="10dp"/>
<padding android:left="0dp"
    android:bottom="0dp"
    android:right="0dp"
    android:top="0dp"/>
</shape>

活动代码:

public class MainActivity extends AppCompatActivity {

SearchView searchView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Get search view and modify it to our needs
    searchView = (SearchView) findViewById(R.id.search_view);
    searchView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.onActionViewExpanded();
        }
    });
    //int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
    //int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
    int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_badge", null, null);
    View searchPlate = searchView.findViewById(searchPlateId);
    //View searchPlate = searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchPlate.setBackgroundResource(R.drawable.bg_white_rounded);
}
}

评论的行是我已经尝试但没有用的东西。谢谢!

只需给padding = corner radius,因为实际SearchView隐藏了角落背景会将其设置为后退,所以填充会成功

绘制/ bg_white_rounded.xml:

  <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#ffffff"/>
    <corners android:radius="8dp"/>
    <padding android:left="8dp"
        android:bottom="8dp"
        android:right="8dp"
        android:top="8dp"/>
    </shape>

虽然rajan ks(谢谢!)答案有效,但它与100%的设计模型不相似(填充自然会增加SearchView的大小而不会增加包含的EditText的大小)。

我找到的解决方案是:在MainActivity.java中,更改search_edit_frame,search_plate和search_bar:

    int searchFrameId = searchView.getContext().getResources().getIdentifier("android:id/search_edit_frame", null, null);
    View searchFrame = searchView.findViewById(searchFrameId);
    searchFrame.setBackgroundResource(R.drawable.bg_white_rounded);

    int searchPlateId = searchView.getContext().getResources().getIdentifier("android:id/search_plate", null, null);
    View searchPlate = findViewById(searchPlateId);
    searchPlate.setBackgroundResource(R.drawable.bg_white_rounded);

    int searchBarId = searchView.getContext().getResources().getIdentifier("android:id/search_bar", null, null);
    View searchBar = findViewById(searchBarId);
    searchBar.setBackgroundResource(R.drawable.bg_white_rounded);

这导致SearchView看起来与模型完全一样。

我只能使用带有androidx SearchView的xml来实现所需的结果

<androidx.appcompat.widget.SearchView
    ...
    app:queryBackground="@drawable/bg_white_rounded"
    app:submitBackground="@drawable/bg_white_rounded"
    android:background="@drawable/bg_white_rounded"/>
