自定义（标题栏）TitleBar样式

这段时间比较闲，整理了下自己以前的自定义标题栏，比较简单，如有更好的写法，欢迎批评指教。
样式如下：

1.布局文件

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/top_tab_height"
    android:background="@color/c_ff"
    android:orientation="horizontal">

  
    <TextView
        android:id="@+id/tv_back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:drawableLeft="@drawable/back_blue"
        android:drawablePadding="@dimen/dp_6"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:text="@string/back"
        android:textColor="@color/c_0042ff"
        android:textSize="@dimen/dp_14" />

    <TextView
        android:textStyle="bold"
        android:id="@+id/include_tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:ellipsize="end"
        android:maxEms="12"
        android:singleLine="true"
        android:textColor="@color/f_33"
        android:textSize="18dp" />

    <TextView
        android:id="@+id/tv_right"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:gravity="center"
        android:padding="10dp"
        android:textSize="16dp" />

    <ImageView
        android:id="@+id/img_right"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_alignParentRight="true"
        android:layout_gravity="right"
        android:paddingLeft="12dp"
        android:paddingRight="12dp"
        android:visibility="gone" />

    <View
        android:layout_width="match_parent"
        android:layout_height="1px"
        android:layout_gravity="bottom"
        android:background="@color/c_e5" />

</FrameLayout>

2.自定义代码

/**
 * @author J.query
 * @date 2016/5/24
 * @email [email protected]
 */
public class TopTitleBar extends LinearLayout {

    private TextView mLeftTv;
    private TextView mRightTv;
    private ImageView mRightImg;

    public TopTitleBar(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        LayoutInflater.from(context).inflate(R.layout.include_title, this, true);

        TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.Top_title);

        boolean mShowLeft = a.getBoolean(R.styleable.Top_title_showLeft, true);
        mLeftTv = (TextView) findViewById(R.id.tv_back);
        if (!mShowLeft) {
            mLeftTv.setVisibility(GONE);
        }

        String rightStr = a.getString(R.styleable.Top_title_rightTitle);
        mRightTv = (TextView) findViewById(R.id.tv_right);
        if (rightStr != null) {
            mRightTv.setText(rightStr);
        }

        String mTitle = a.getString(R.styleable.Top_title_title);
        TextView mTvTitle = (TextView) findViewById(R.id.include_tv);
        if (mTitle != null) {
            mTvTitle.setText(mTitle);
        }

        int mResourceId = a.getResourceId(R.styleable.Top_title_rightRes, -1);
        mRightImg = (ImageView) findViewById(R.id.img_right);
        if (mResourceId != -1) {
            mRightImg.setVisibility(VISIBLE);
            mRightImg.setImageResource(mResourceId);
        }

        a.recycle();
    }

    public void setLeftVisible(boolean b) {
        if (mLeftTv != null)
            mLeftTv.setVisibility(b ? VISIBLE : GONE);
    }

    public void setRightTvVisible(boolean b) {
        if (mRightTv != null)
            mRightTv.setVisibility(b ? VISIBLE : GONE);
    }

    public void setRightVisible(boolean b) {
        if (mRightImg != null)
            mRightImg.setVisibility(b ? VISIBLE : GONE);
    }
}


3. attrs.xml  文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="Top_title">
        <attr name="title" format="string" />
        <attr name="rightTitle" format="string" />
        <attr name="showLeft" format="boolean" />
        <attr name="rightRes" format="reference" />
    </declare-styleable>
</resources>





4.使用方式

布局文件使用示例：
<.......widgets.TopTitleBar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:title="标题" />

Activity使用示例：

我是把他集成到BaseActivity里面的，避免重复的写返回键

  public void setTitle(String title) {
        TextView tvTitle = (TextView) findViewById(R.id.include_tv);
        tvTitle.setText(title);
        findViewById(R.id.tv_back).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
    }
