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; } }); } }
