自定义SearchView实现即时查询

1.效果图，输入关键字时会根据关键字改变而更新数据。

2.其布局文件和2个小图标del.png和searchview.png，布局文件如下：高度已固定为46dp。

<?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="46dp">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="46dp"
        android:orientation="horizontal">  
     
      <Button
            android:id="@+id/btn_search"
            android:layout_width="20dp"
            android:layout_height="20dp"
            android:layout_gravity="right|center_vertical"
            android:layout_margin="10dp"
            android:background="@mipmap/search"/>  
      <EditText
            android:id="@+id/et_search"
            android:layout_width="0dp"
            android:layout_height="fill_parent"
            android:layout_marginLeft="10dp"
            android:layout_weight="4"
            android:background="@null"
            android:gravity="center_vertical"
            android:hint="@string/searchViewHint"
            android:imeOptions="actionSearch"
            android:singleLine="true"
            android:textColor="@color/colorHomeBar"
            android:textColorHint="@color/colorSingerName"
            android:textSize="17sp"/>  
      <Button
            android:id="@+id/bt_clear"
            android:layout_width="25dp"
            android:layout_height="25dp"
            android:layout_gravity="right|center_vertical"
            android:layout_margin="10dp"
            android:background="@mipmap/del"/>  
     </LinearLayout>  
</LinearLayout>

3.SearchView的样式：圆角+描边

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <!-- 角度 -->
    <corners android:radius="10dp"/>
    <!-- 填充色 -->
    <solid android:color="#ffffff"/>
    <!-- 描边 设置线宽及颜色 -->
    <stroke android:color="@color/colorAccent"
        android:width="2dp"/>
</shape>

    }

    }

        public void run() {
            times2= System.currentTimeMillis();
            /**
             * 超过800ms没有文字变化，则认为输入完成，开始自动搜索。

            if(times2-times1>800&&times1!=0){
                Log.d(TAG, "run: "+"监听超时");
                times1=0;
                onQueryTextListener.MyonQueryTextChange(""+str);
            }
        }
    };

}

5.使用

  <com.multak.cookaraclient.view.MySearchView
            android:id="@+id/searchView_Favo"
            android:layout_width="match_parent"
            android:layout_height="46dp"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="8dp"
            android:layout_marginTop="8dp"
            android:background="@drawable/searviewtest" />

searchView_record = (MySearchView) view.findViewById(R.id.searchView_record);
        searchView_record.clearFocus();
       
        searchView_record.setSearchViewListener(new MySearchView.MyOnQueryTextListener() {
            @Override
            public void MyonQueryTextChange(String value) {
　　　　　　　　/** 自动搜索的处理**/
            }

            @Override
            public void MyonQueryTextSubmit(String value) {
　　　　　　　　/*** 点击提交时的处理**/
            }
        });
