1.編寫佈局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/commonsdk_ll_search_item"
    android:layout_width="match_parent"
    android:layout_height="48dp"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    android:paddingBottom="7dp"
    android:paddingTop="7dp">

    <FrameLayout
        android:layout_width="48dp"
        android:layout_height="match_parent">

        <ImageView
            android:id="@+id/commonsdk_iv_search_back"

        <TextView
            android:id="@+id/commonsdk_tv_search_back"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:visibility="gone" />
    </FrameLayout>

    <LinearLayout
        android:id="@+id/commonsdk_ll_search"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="@drawable/circle_conversation_search_bg"
        android:gravity="center_vertical"
        android:paddingBottom="4dp"
        android:paddingLeft="14dp"
        android:paddingRight="14dp"
        android:paddingTop="4dp">

        <EditText
            android:id="@+id/commonsdk_et_search_content"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@null"
            android:gravity="center_vertical"
            android:imeOptions="actionSearch"
            android:inputType="text"
            android:maxLines="1"
            android:singleLine="true"
            android:textColor="#333333"
            android:textColorHint="#cccccc"
            android:textSize="15sp" />
    </LinearLayout>

    <FrameLayout
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:paddingLeft="9dp"
        android:paddingRight="14dp">

        <ImageView
            android:id="@+id/commonsdk_iv_search_cancle"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:gravity="center_vertical"
            android:src="@drawable/arrow_left_back"
            android:visibility="gone" />

        <TextView
            android:id="@+id/commonsdk_tv_search_cancle"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:gravity="center_vertical"
            android:textColor="#A1B2C6"
            android:textSize="15sp" />
    </FrameLayout>
</LinearLayout>

2.自定義屬性
<!--搜尋框 -->
<declare-styleable name="CustomSearchView">
    <attr name="search_hint" format="string"></attr>
    <attr name="search_left_icon" format="reference"></attr>
    <attr name="search_right_icon" format="reference"></attr>
    <attr name="search_left_text" format="string"></attr>
    <attr name="search_right_text" format="string"></attr>
</declare-styleable>
 

3.自定義控制元件

import android.content.Context;
import android.content.res.TypedArray;
import android.support.annotation.Nullable;
import android.text.Editable;
import android.text.TextWatcher;

import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.inputmethod.EditorInfo;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import com.dejun.commonsdk.R;
