Android 自定义控件之app标题栏的封装

在app的开发中，每一个页面都有上面的标题栏，总不能在开发的过程中没个界面都写一个标题栏的布局，所以为了开发的方便，将该标题栏进行的封装，以后在实际的开发工作中，也可以将该封装好的标题栏控件直接拿来使用，当然肯定是需要更改里面的布局文件的

下面贴出的是布局文件

            tvRightComplete = (TextView) v.findViewById(R.id.tvRightComplete);
        }
    }
}

在使用中如何使用呢，接下来看在项目中  布局文件的引用

    <包名.MyAppTitle
        android:id="@+id/myNewAppTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </包名.MyAppTitle>

下面是在activity中如何初始化该标题的代码

private void setMyAppTitle()
    {
        MyAppTitle mNewAppTitle = (MyAppTitle) this.findViewById(R.id.myNewAppTitle);

        mNewAppTitle.initViewsVisible(true, true, false, true);

        mNewAppTitle.setAppTitle(getString(R.string.toptitle_tool_MySuggestActivity));
        mNewAppTitle.setRightTitle("提交");
        mNewAppTitle.setOnLeftButtonClickListener(new OnLeftButtonClickListener()
        {
            @Override
            public void onLeftButtonClick(View v)
            {
                onBackPressed();
            }
        });

        mNewAppTitle.setOnRightButtonClickListener(new OnRightButtonClickListener()
        {
            @Override
            public void OnRightButtonClick(View v)
            {
                //TODO
            }
        });
    }

这就是全部的代码了 在这里贴出来  方便以后的学习
