自定义ToolBar，实现最大的自由度

一、自定义控件

/** * 自定义的标题 */public class TitleLayout extends RelativeLayout {    private TextView tvTitle;    private TextView tvRight;    public TitleLayout(Context context, AttributeSet attrs) {        super(context, attrs);        LayoutInflater.from(context).inflate(R.layout.titlebar_bfmg, this);        findViewById(R.id.tx_back).setOnClickListener(new OnClickListener() {//内部处理返回键            @Override            public void onClick(View v) {                ((Activity) getContext()).finish();            }        });        tvTitle = (TextView) findViewById(R.id.tx_titleName);        tvRight = (TextView) findViewById(R.id.tv_right);        // 获得自定义属性        TypedArray a = context.obtainStyledAttributes(attrs,                R.styleable.TitleLayout);        boolean isRightVisible = a.getBoolean(R.styleable.TitleLayout_isRightVisible, false);        tvTitle.setText(a.getString(R.styleable.TitleLayout_titleString));        tvRight.setText(a.getString(R.styleable.TitleLayout_rightString));        if (isRightVisible) {            tvRight.setVisibility(VISIBLE);        } else {            tvRight.setVisibility(INVISIBLE);        }        tvRight.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {//设置右边点击事件                if (rightOnClickListener != null) {                    rightOnClickListener.onClick();                }            }        });    }    public interface RightOnClickListener {        public void onClick();    }    RightOnClickListener rightOnClickListener;    public void setRightOnClickListener(RightOnClickListener rightOnClickListener) {        this.rightOnClickListener = rightOnClickListener;    }}

二、布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/title"    android:layout_width="match_parent"    android:layout_height="44dp"    android:background="@color/white">    <TextView        android:id="@+id/tx_back"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerVertical="true"        android:clickable="true"        android:background="@drawable/back_btn_selector"/>    <TextView        android:id="@+id/tx_titleName"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerInParent="true"        android:gravity="center"        android:text="收银台"        android:textColor="#684E75"        android:textSize="@dimen/top_bar_title_size"/>    <TextView        android:id="@+id/tv_right"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:layout_alignParentRight="true"        android:gravity="center"        android:paddingLeft="12dp"        android:paddingRight="@dimen/common_dp12"        android:textColor="#684E75"        android:visibility="invisible"        android:clickable="true"        /></RelativeLayout>

三、属性（attr.xml）

<declare-styleable name="TitleLayout">    <attr name="titleString" format="string" />    <attr name="isRightVisible" format="boolean"/>    <attr name="rightString" format="string"/></declare-styleable>
