简单实现顶部和底部工具栏

转自：eoe.Android开发者门户

我们今天讲的主要就是android屏幕上的顶部与底部的工具栏，这样我们就可以在一个界面上实现很多种功能了，这样我们的用户用起来也比较好用，至于上面都有什么功能，那就看大家怎么来实现了，也不多说了，我们还是先来看看效果图：

这两个工具栏全是用布局来实现的。底部工具栏布局代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/bottom"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
<TextView
    android:id="@+id/edit"
    android:text="测试"
    android:gravity="center_horizontal"
    android:drawableTop="@drawable/ic_dialog_alert"
    android:layout_alignParentLeft="true"
    android:layout_width="80dip"
    android:layout_height="wrap_content">
</TextView>

<TextView
    android:id="@+id/menu2"
    android:text="测试"
    android:gravity="center_horizontal"
    android:drawableTop="@drawable/ic_dialog_dialer"
    android:layout_toRightOf="@id/edit"
    android:layout_width="80dip"
    android:layout_height="wrap_content">
</TextView>

<TextView
    android:id="@+id/effect"
    android:text="测试"
    android:gravity="center_horizontal"
    android:drawableTop="@drawable/ic_dialog_email"
    android:layout_toRightOf="@id/menu2"
    android:layout_width="80dip"
    android:layout_height="wrap_content">
</TextView>

<TextView
    android:id="@+id/menu3"
    android:text="测试"
    android:gravity="center_horizontal"
    android:drawableTop="@drawable/ic_dialog_info"
    android:layout_toRightOf="@id/effect"
    android:layout_width="80dip"
    android:layout_height="wrap_content">

</TextView>
</RelativeLayout>

顶部工具栏布局代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/top"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

<ImageView
    android:id="@+id/undo"
    android:src="@drawable/ic_dialog_map"
    android:layout_alignParentLeft="true"
    android:layout_width="80dip"
    android:layout_height="wrap_content">

</ImageView>

<ImageView
    android:id="@+id/save"
    android:src="@drawable/ic_dialog_menu_generic"
    android:layout_toRightOf="@id/undo"
    android:layout_width="80dip"
    android:layout_height="wrap_content">
</ImageView>

<ImageView
    android:id="@+id/share"
    android:src="@drawable/ic_dialog_time"
    android:layout_toRightOf="@id/save"
    android:layout_width="80dip"
    android:layout_height="wrap_content">

</ImageView>

<ImageView
    android:id="@+id/redo"
    android:src="@drawable/ic_dialog_usb"
    android:layout_toRightOf="@id/share"
    android:layout_width="80dip"
    android:layout_height="wrap_content">

</ImageView>

</RelativeLayout>

主窗口布局代码：

< ?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout_topmenu"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true">

<include layout="@layout/top_menu" />
</RelativeLayout>

<TextView
    android:id="@+id/txt1"
    android:text="asdfasdfas"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/layout_topmenu">
</TextView>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true">
<include layout="@layout/bottom_menu" />

</RelativeLayout>
</RelativeLayout>

最后我们来看看主程序代码：

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.view.View.OnTouchListener;
import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {
    TextView txt1;
    TextView edittv;
    ImageView imgbtn;
    boolean isFirst = true;
    boolean istopFirst = true;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);

        edittv = (TextView)findViewById(R.id.edit);
        txt1 = (TextView)findViewById(R.id.txt1);
        imgbtn = (ImageView)findViewById(R.id.undo);
        edittv.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(isFirst) {
                    txt1.setText("编辑");
                    edittv.setBackgroundDrawable(getResources().getDrawable(R.drawable.item_background));
                    isFirst = false;
                }else {
                    txt1.setText("退出编辑");
                    edittv.setBackgroundDrawable(getResources().getDrawable(R.drawable.touming));
                    isFirst = true;
                }
                return false;
            }
        });
        imgbtn.setOnTouchListener(new OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(istopFirst) {
                    txt1.setText("编辑");
                    istopFirst = false;
                }else {
                    txt1.setText("退出编辑");
                    istopFirst = true;
                }
                return false;
            }
        });
    }
 
}
