思路及实现步骤

1.定义标题栏布局
2.自定义TitleActivity控制标题栏按钮监听
3.在TitleActivity中实现标题栏以下内容切换

效果如下：

首先定义标题栏

layout_title.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/layout_titlebar"    android:layout_width="match_parent"    android:layout_height="52dp"    android:background="#ed4255">    <TextView        android:id="@+id/text_title"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:ellipsize="marquee"        android:gravity="center_horizontal|center"        android:singleLine="true"        android:text="标题栏"        android:textColor="#ffffffff"        android:textSize="20dp" />    <Button        android:id="@+id/button_backward"        android:layout_width="70dp"        android:layout_height="match_parent"        android:background="@drawable/title_button_selector"        android:drawableLeft="@drawable/back_arrow"        android:drawablePadding="6dp"        android:ellipsize="end"        android:gravity="center"        android:onClick="onClick"        android:paddingLeft="5dp"        android:singleLine="true"        android:text="返回"        android:textColor="#ffffffff"        android:textSize="18dp"        android:visibility="invisible" />    <Button        android:id="@+id/button_forward"        android:layout_width="70dp"        android:layout_height="match_parent"        android:layout_alignParentRight="true"        android:background="@drawable/title_button_selector"        android:drawablePadding="6dp"        android:ellipsize="end"        android:gravity="center"        android:onClick="onClick"        android:paddingLeft="5dp"        android:singleLine="true"        android:text="提交"        android:textColor="#ffffffff"        android:textSize="18dp"        android:visibility="invisible" /></RelativeLayout>

定义界面的标题栏和标题栏以下内容的布局
此处使用<include>标签引入标题栏，且下方有定义一个空的FrameLayout的布局。

activity_title.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <include layout="@layout/layout_title" />    <FrameLayout        android:id="@+id/layout_content"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#fff"/></LinearLayout>

定义TitleActivity布局以及按钮

TitleActivity.java

public class TitleActivity extends Activity implements View.OnClickListener {    //private RelativeLayout mLayoutTitleBar;    private TextView mTitleTextView;    private Button mBackwardbButton;    private Button mForwardButton;    private FrameLayout mContentLayout;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setupViews();   //加载 activity_title 布局 ，并获取标题及两侧按钮    }    private void setupViews() {        super.setContentView(R.layout.activity_title);        mTitleTextView = (TextView) findViewById(R.id.text_title);        mContentLayout = (FrameLayout) findViewById(R.id.layout_content);        mBackwardbButton = (Button) findViewById(R.id.button_backward);        mForwardButton = (Button) findViewById(R.id.button_forward);    }    /**     * 是否显示返回按钮     *     * @param backwardResid 文字     * @param show          true则显示     */    protected void showBackwardView(int backwardResid, boolean show) {        if (mBackwardbButton != null) {            if (show) {                mBackwardbButton.setText(backwardResid);                mBackwardbButton.setVisibility(View.VISIBLE);            } else {                mBackwardbButton.setVisibility(View.INVISIBLE);            }        } // else ignored    }    /**     * 提供是否显示提交按钮     *     * @param forwardResId 文字     * @param show         true则显示     */    protected void showForwardView(int forwardResId, boolean show) {        if (mForwardButton != null) {            if (show) {                mForwardButton.setVisibility(View.VISIBLE);                mForwardButton.setText(forwardResId);            } else {                mForwardButton.setVisibility(View.INVISIBLE);            }        } // else ignored    }    /**     * 返回按钮点击后触发     *     * @param backwardView     */    protected void onBackward(View backwardView) {        Toast.makeText(this, "点击返回，可在此处调用finish()", Toast.LENGTH_LONG).show();        //finish();    }    /**     * 提交按钮点击后触发     *     * @param forwardView     */    protected void onForward(View forwardView) {        Toast.makeText(this, "点击提交", Toast.LENGTH_LONG).show();    }    //设置标题内容    @Override    public void setTitle(int titleId) {        mTitleTextView.setText(titleId);    }    //设置标题内容    @Override    public void setTitle(CharSequence title) {        mTitleTextView.setText(title);    }    //设置标题文字颜色    @Override    public void setTitleColor(int textColor) {        mTitleTextView.setTextColor(textColor);    }    //取出FrameLayout并调用父类removeAllViews()方法    @Override    public void setContentView(int layoutResID) {        mContentLayout.removeAllViews();        View.inflate(this, layoutResID, mContentLayout);        onContentChanged();    }    @Override    public void setContentView(View view) {        mContentLayout.removeAllViews();        mContentLayout.addView(view);        onContentChanged();    }    /* (non-Javadoc)     * @see android.app.Activity#setContentView(android.view.View, android.view.ViewGroup.LayoutParams)     */    @Override    public void setContentView(View view, ViewGroup.LayoutParams params) {        mContentLayout.removeAllViews();        mContentLayout.addView(view, params);        onContentChanged();    }    /* (non-Javadoc)     * @see android.view.View.OnClickListener#onClick(android.view.View)     * 按钮点击调用的方法     */    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.button_backward:                onBackward(v);                break;            case R.id.button_forward:                onForward(v);                break;            default:                break;        }    }}

MainActivity中调用时直接 extends TitleActivity，使用在TitleActivity中定义的方法

public class MainActivity extends TitleActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        setTitle("标题栏");        showBackwardView(R.string.text_back,true);        showForwardView(R.string.text_forward,true);    }}
