Android Widget组件应用学习是本文要介绍的内容,主要是来了解并学习Android Widget组件应用,具体内容的学习来看本文详解。
这里是Android基本组件Button和Tab_Widget的简单应用,通过点击Tab1、Tab2、Tab3、来切换查看内容
图为加入TabView按钮的Activity和点击Tab切换效果演示
项目名为:Tab
代码如下:
package com.tab.demo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
private Button button; //构建按钮对象
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button=(Button)findViewById(R.id.tab_demo_button); //实例化对象,联系到布局文件
button.setOnClickListener(new Button.OnClickListener() {
//设置监听器,监听点击事件
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(MainActivity.this, TabDemoActivity.class);
startActivity(intent); //实现点击跳转
}
});
}
}
//跳转到TabDemoActivity的代码
package com.tab.demo;
import android.app.TabActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.TabHost;
public class TabDemoActivity extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost tabHost = getTabHost(); //构造一个Tab标签容器TabHost
LayoutInflater.from(this).inflate(R.layout.tab_demo,
tabHost.getTabContentView(), true);
tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab1")
.setContent(R.id.view1)); //分别把构造好的标签放入TabHost里面
tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab2")
.setContent(R.id.view2));
tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("Tab3")
.setContent(R.id.view3));
}
}
