实现功能:

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区域的切换;

4)新建Activity继承TitleActivity,实现重用标题栏效果。


实现步骤:

1. 新建一个工程,命名为TitleActivityDemo,Activity命名为TitleActivity;

2. 实现如图效果

分为:返回按钮、返回键、标题、提交

3. 设置返回按钮监听,并toast;

1)设置左上角箭头和返回文案区域点击事件的监听,toast提示如图文案;

2)设置提交文字的点击事件监听并toast提示“我是提交按钮”;

4). 实现标题栏下方内容区域;

5)编写MainActivity类继承TitleActivity,实现如图整体逻辑。


效果图:

   

android 两侧菜单 android顶部菜单_自定义顶部标题栏

  

android 两侧菜单 android顶部菜单_android_02

  

android 两侧菜单 android顶部菜单_自定义组合控件_03


功能代码:

1.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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- 首先定义标题栏 -->
    <RelativeLayout
        android:id="@+id/biaoti"
        android:layout_width="match_parent"
        android:layout_height="58dp"
        android:background="#ed4255">
        <TextView
            android:text="标题栏"
            android:id="@+id/text_title"
            android:textSize="21sp"
            android:textColor="#fff"
            android:gravity="center"
            android:singleLine="true"
            android:ellipsize="marquee"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <Button
            android:id="@+id/button_backward"
            android:layout_width="70dp"
            android:layout_height="match_parent"
            android:drawableLeft="@drawable/back_arrow"
            android:drawablePadding="6dp"
            android:background="#ed4255"
            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:drawablePadding="6dp"
            android:background="#ed4255"
            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>

    <TextView
        android:text="Android"
        android:textSize="28sp"
        android:gravity="center"
        android:layout_below="@+id/biaoti"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</RelativeLayout>



2.activity_title.xml  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。


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--    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。  -->
    <include layout="@layout/layout_title"></include>

    <FrameLayout
        android:background="#fff"
        android:id="@+id/layout_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </FrameLayout>

</LinearLayout>



3.TitleActivity.java  定义TitleActivity布局以及按钮


package com.bwie.title;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.FrameLayout;
import android.widget.TextView;
import android.widget.Toast;

/**
 * 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区域的切换;
 */
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_SHORT).show();
        //finish();
    }

    /**
     * 提交按钮点击后触发
     *
     * @param forwardView
     */
    protected void onForward(View forwardView) {
        Toast.makeText(this, "我是提交按钮", Toast.LENGTH_SHORT).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;
        }
    }
}



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

package com.bwie.title;
import android.os.Bundle;
/**
 * 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);
    }
}



5. 在string.xml中写入以下代码:

<resources>
    <string name="text_back">返回</string>
    <string name="text_forward">提交</string>
</resources>



6.布局中需要引用的左箭头图片
