Android实验7-使用Intent和Android应用资源答案.doc

一、实验名称：实验7 使用Intent和Android应用资源二、实验日期：2016-04-15三、实验目的：1、掌握Intent的几种常用的属性。2、Android系统内置Intent的使用。3、定义、使用Android应用的资源。四、实验用的仪器和材料：Windows+Eclipse+jdk+sdk+adt五、实验的步骤和方法：实验一: Intent的Action属性的使用Main.xml Second.xml Week07_01Activity.javapackage com.week07.lab01;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class Week07_01Activity extends Activity /定义一个Action常量final static String JHY_ACTION = ent.action.JHY_ACTION; /定义一个Category常量final static String JHY_CATEGORY = ent.category.JHY_CATEGORY; public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); Button bn = (Button) findViewById(R.id.bn); bn.setOnClickListener(new OnClickListener() public void onClick(View arg0) Intent intent = new Intent(); /设置Action属性 intent.setAction(Week07_01Activity.JHY_ACTION); /添加Category属性 intent.addCategory(Week07_01Activity.JHY_CATEGORY); startActivity(intent); ); SecondActivity.javapackage com.week07.lab01;import java.util.Set;import android.app.Activity;import android.os.Bundle;import android.widget.EditText;public class SecondActivity extends Activity public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState);setContentView(R.layout.second);EditText show =(EditText) findViewById(R.id.show);/获取该Activity对应的Intent的Action属性String action = getIntent().getAction();/显示Action属性show.setText(Action为:+action);EditText cate = (EditText) findViewById(R.id.cate);/ 获取该Activity对应的Intent的Category属性Set cates = getIntent().getCategories();/ 显示Action属性cate.setText(Category属性为： + cates); AndroidManifest.xml 实验二: Android系统内置Intent使用，自己编写布局文件main.xml代码Main.xml Week07_02Activity.javapackage com.week07.lab02;import android.app.Activity;import android.content.Intent;import .Uri;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class Week07_02Activity extends Activity /* Called when the activity is first created. */ Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); Button bn = (Button)findViewById(R.id.bn); /为bn按钮添加一个监听器 bn.setOnClickListener(new OnClickListener()public void onClick(View v) /创建IntentIntent intent = new Intent();String data = ;/根据指定字符串解析出Uri对象Uri uri =Uri.parse(data);/ 为Intent设置Action属性intent.setAction(Intent.ACTION_VIEW);/设置Data属性intent.setData(uri);startActivity(intent); ); Button edit = (Button) findViewById(R.id.edit);/ 为edit按钮添加一个监听器edit.setOnClickListener(new OnClickListener() public void onClick(View v) / 创建IntentIntent intent = new Intent();/ 为Intent设置Action属性intent.setAction(Intent.ACTION_EDIT);String data = content:/com.android.contacts/contacts/1;/根据指定字符串解析出Uri对象Uri uri =Uri.parse(data);/设置Data属性intent.setData(uri);startActivity(intent););Button call = (Button) findViewById(R.id.call);/ 为edit按钮添加一个监听器call.setOnClickListener(new OnClickListener() public void onClick(View v) / 创建IntentIntent intent = new Intent();/ 为Intent设置Action属性（动作为：拨号）intent.setAction(Intent.ACTION_DIAL); String data = tel/ 根据指定字符串解析出Uri对象Uri uri =Uri.parse(data); / 设置Data属性intent.setData(uri); startActivity(intent);); 实验三：Android字符串资源，颜色资源，数组资源等的使用程序，补充代码Main.xml Colors.xml #F00 #0F0 #00F #0FF #F0F #FF0 #07F #70F #F70 Dimens.xml 8dp 60dp 66dp 18dpArrays.xml color/c1 color/c2 color/c3 color/c4 color/c5 color/c6 color/c7 color/c8 color/c9 string/c1 string/c2 string/c3 string/c4 string/c5 string/c6 string/c7 string/c8 string/c9 疯狂Java讲义 疯狂Ajax讲义 疯狂Android讲义 Strings.xml week07-03 Android应用资源的使用 F00 0F0 00F 0FF F0F FF0 07F 70F F70Week07_03Activity.javapackage com.week07.lab03;import android.app.Activity;import android.content.res.Resources;import android.content.res.TypedArray;import android.os.Bundle;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.GridView;import android.widget.TextView;public class Week07_03Activity extends Activity / 获取系统定义的数组资源String texts;
