/定義一個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(); /設(shè)置Action屬性 intent.setAction(Week07_01Activity.JHY_ACTION); /添加Category屬性 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);/獲取該Activity對應(yīng)的Intent的Action屬性String action = getIntent().getAction();/顯示Action屬性show.setText(Action為:+action);EditText cate = (EditText) findViewById(R.id.cate);/ 獲取該Activity對應(yīng)的Intent的Category屬性Set cates = getIntent().getCategories();/ 顯示Action屬性cate.setText(Category屬性為： + cates); AndroidManifest.xml 實驗二: Android系統(tǒng)內(nèi)置Intent使用，自己編寫布局文件main.xml代碼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);

String data = tel/ 根據(jù)指定字符串解析出Uri對象Uri uri =Uri.parse(data); / 設(shè)置Data屬性intent.setData(uri); startActivity(intent);); 實驗三：Android字符串資源，顏色資源，數(shù)組資源等的使用程序，補(bǔ)充代碼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 瘋狂Java講義 瘋狂Ajax講義 瘋狂Android講義 Strings.xml week07-03 Android應(yīng)用資源的使用 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 / 獲取系統(tǒng)定義的數(shù)組資源String texts;
