今天是安全卫士学习第二天，主要涉及以下内容：
1 安全卫士主页面的布局
其中涉及gridview的使用,包括布局文件的引用，以及自定义控件textview
<?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" >
<TextView
android:gravity="center"
android:background="#8866ff00"
android:id="@+id/tv_function_list"
android:layout_width="fill_parent"
android:layout_height="55dip"
android:text="功能列表"
android:textSize="22sp"
android:textColor="#000000"/>
<com.djf.mobilesafty.ui.FocusdTextView
android:layout_marginTop="10dip"
android:singleLine="true"
android:ellipsize="marquee"
android:textSize="22sp"
android:text="距离季前赛还有11天，欲知详细信息，请登录查看详细信息，新赛季更精彩，值得期待··"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<GridView
android:verticalSpacing="30dip"
android:layout_marginTop="60dip"
android:numColumns="3"
android:id="@+id/gv_item_home"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
package com.djf.mobilesafty;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
public class HomeActivity extends Activity {
private GridView gv_item_home;
private Myadapter adapter;
private String[] names = {
"手机防盗","通讯卫士","软件管理",
"进程管理","流量统计","手机杀毒",
"缓存清理","高级工具","设置中心"};
private static int[] ids = {
R.drawable.safe,R.drawable.callmsgsafe,R.drawable.app,
R.drawable.taskmanager,R.drawable.netmanager,R.drawable.trojan,
R.drawable.sysoptimize,R.drawable.atools,R.drawable.settings
};
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
gv_item_home = (GridView) findViewById(R.id.gv_item_home);
adapter = new Myadapter();
gv_item_home.setAdapter(adapter);
gv_item_home.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
switch (position) {
case 8:
Intent intent = new Intent(HomeActivity.this,SetActivity.class);
startActivity(intent);
break;
default:
break;
}
}
});
}
public class Myadapter extends BaseAdapter{
@Override
public int getCount() {
// TODO Auto-generated method stub
return names.length;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view = View.inflate(HomeActivity.this, R.layout.list_item_home, null);
TextView tv_item = (TextView) view.findViewById(R.id.tv_item);
ImageView iv_item = (ImageView) view.findViewById(R.id.iv_item);
tv_item.setText(names[position]);
iv_item.setImageResource(ids[position]);
return view;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
}
}
2 设置中心的布局，
其中涉及自定义组件，其中组件中涉及两个textview，一个checkbox,一个view，以及对自定义组件的动作处理，信息的改变
package com.djf.mobilesafty;
import com.djf.mobilesafty.ui.SetItemView;
import android.app.Activity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
public class SetActivity extends Activity {
private SetItemView setItemView;
private SharedPreferences sp;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set);
sp = getSharedPreferences("config", MODE_PRIVATE);
setItemView = (SetItemView) findViewById(R.id.siv_update);
boolean update = sp.getBoolean("update", false);
if (update) {
//自动升级已经开启
setItemView.SetChecked(true);
setItemView.SetDesc("开启升级");
}
else {
//自动升级已经关闭
setItemView.SetChecked(false);
setItemView.SetDesc("关闭升级");
}
setItemView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Editor editor = sp.edit();
// 组件已经被选中
if (setItemView.isChecked()) {
// 设置组件处于非选中状态，关闭升级
setItemView.SetChecked(false);
setItemView.SetDesc("关闭升级");
editor.putBoolean("update", false);
} else // 组件没有被选中
{
setItemView.SetChecked(true);
setItemView.SetDesc("开启升级");
editor.putBoolean("update", true);
}
editor.commit();
}
});
}
}
自定义组件布局
<?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" >
<TextView
android:layout_width="fill_parent"
android:layout_height="55dip"
android:background="#8866ff00"
android:gravity="center"
android:text="设置中心"
android:textColor="#000000"
android:textSize="22sp" />
<com.djf.mobilesafty.ui.SetItemView
android:id="@+id/siv_update"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</com.djf.mobilesafty.ui.SetItemView>
</LinearLayout>
