Android Intent传递对象和ArrayList【大明进化

以前做项目的时候，需要Intent传递复杂类型，例如：数组，ArrayList类型，传递类对象，今天抽空写了个例子，方便以后用的时候查询！有问题可以留言；

程序主界面 ： 点击list按钮传递数据：

点击parcelable传递数据：点击serializable传递数据：

下面看代码：

一、MainAcitivty。java类的代码：

<span style="font-size: 16px; color: #000000;">package com.cn.daming; import java.io.Serializable; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import android.app.Activity; import android.app.ListActivity; import android.content.Intent; import android.graphics.Color; import android.graphics.drawable.GradientDrawable; import android.graphics.drawable.GradientDrawable.Orientation; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity implements Serializable{ private static final long serialVersionUID = 1L; private String s_name; private int s_number; private String s_sex; private Button list_Button; private Button ser_Button; private Button par_Button; private ArrayList<String> m_list; public final static String PAR_KEY = "com.cn.daming.parcelable"; public final static String SER_KEY = "com.cn.daming.serializable"; public final static String LIST_KEY = "com.cn.daming.ArrayList"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initlist(); drawBackground(); initList_Button(); initPar_Button(); inintSer_Button(); } public void initlist() { m_list = new ArrayList<String>(); m_list.add("大明ArrayList"); m_list.add("年龄:25岁"); m_list.add("性别：男"); } public void drawBackground() { GradientDrawable grad = new GradientDrawable( Orientation.TL_BR, new int[] {Color.rgb(0, 0, 127), Color.rgb(0, 0, 255), Color.rgb(127, 0, 255), Color.rgb(127, 127, 255), Color.rgb(127, 255, 255), Color.rgb(255, 255, 255)} ); this.getWindow().setBackgroundDrawable(grad); } public void initList_Button() { list_Button = (Button)findViewById(R.id.list_button); list_Button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { Intent list_intent = new Intent(); list_intent.putStringArrayListExtra(LIST_KEY, m_list); list_intent.setClass(MainActivity.this, ShowListView.class); startActivity(list_intent); } }); } public void initPar_Button() { par_Button = (Button)findViewById(R.id.par_button); par_Button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { Student m_Student = new Student(); m_Student.setName("大明例子"); m_Student.setAge(25); m_Student.setSex("男"); Intent p_Intent = new Intent(MainActivity.this,ShowParView.class); Bundle mBundle = new Bundle(); mBundle.putParcelable(PAR_KEY, m_Student); p_Intent.putExtras(mBundle); startActivity(p_Intent); } }); } public void inintSer_Button() { ser_Button = (Button)findViewById(R.id.ser_button); ser_Button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { MainActivity s_activity = new MainActivity(); s_activity.setS_name("Daming Serlizable!"); s_activity.setS_number(25); s_activity.setS_sex("男"); Intent mIntent = new Intent(MainActivity.this,ShowSerView.class); Bundle mBundle = new Bundle(); mBundle.putInt("state", 3); mBundle.putSerializable(SER_KEY, s_activity); mIntent.putExtras(mBundle); startActivity(mIntent); } }); } public void setS_name(String s_name) { this.s_name = s_name; } public String getS_name() { return s_name; } public void setS_number(int s_number) { this.s_number = s_number; } public int getS_number() { return s_number; } public void setS_sex(String s_sex) { this.s_sex = s_sex; } public String getS_sex() { return s_sex; } }</span>

二、Student。java类的代码：
package com.cn.daming; import android.os.Parcel; import android.os.Parcelable; public class Student implements Parcelable{ private String name; private int age; private String sex; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public static final Parcelable.Creator<Student> CREATOR = new Creator<Student>() { public Student createFromParcel(Parcel source) { Student mStudent = new Student(); mStudent.name = source.readString(); mStudent.age = source.readInt(); mStudent.sex = source.readString(); return mStudent; } public Student[] newArray(int size) { return new Student[size]; } }; @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel parcel, int arg1) { parcel.writeString(name); parcel.writeInt(age); parcel.writeString(sex); } }

三、ShowListView。java类的代码：
package com.cn.daming; import java.util.ArrayList; import android.app.Activity; import android.content.Intent; import android.graphics.Color; import android.graphics.drawable.GradientDrawable; import android.graphics.drawable.GradientDrawable.Orientation; import android.os.Bundle; import android.widget.TextView; public class ShowListView extends Activity{ private Intent list_intent; private ArrayList<String> m_arrayList; private TextView list_textview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.show_list_view); drawBackground(); list_textview = (TextView)findViewById(R.id.list_text_view); list_intent = getIntent(); m_arrayList = list_intent.getExtras().getStringArrayList(MainActivity.LIST_KEY); m_arrayList.get(0); list_textview.setText(m_arrayList.get(0)+" \n"+m_arrayList.get(1)+"\n"+m_arrayList.get(2)); } public void drawBackground() { GradientDrawable grad = new GradientDrawable( Orientation.TL_BR, new int[] {Color.rgb(0, 0, 127), Color.rgb(0, 0, 255), Color.rgb(127, 0, 255), Color.rgb(127, 127, 255), Color.rgb(127, 255, 255), Color.rgb(255, 255, 255)} ); this.getWindow().setBackgroundDrawable(grad); } }

四、ShowParView。java类的代码：
package com.cn.daming; import android.app.Activity; import android.graphics.Color; import android.graphics.drawable.GradientDrawable; import android.graphics.drawable.GradientDrawable.Orientation; import android.os.Bundle; import android.widget.TextView; public class ShowParView extends Activity{ private TextView par_text_view; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.show_par_view); drawBackground(); par_text_view = (TextView)findViewById(R.id.par_text_view); Student p_student = (Student)getIntent().getParcelableExtra(MainActivity.PAR_KEY); par_text_view.setText("姓名: " + p_student.getName()+"\n"+ "年龄: " + p_student.getAge() + "\n" + "性别 : " + p_student.getSex() + "\n" + "类：" + p_student.getClass()); } public void drawBackground() { GradientDrawable grad = new GradientDrawable( Orientation.TL_BR, new int[] {Color.rgb(0, 0, 127), Color.rgb(0, 0, 255), Color.rgb(127, 0, 255), Color.rgb(127, 127, 255), Color.rgb(127, 255, 255), Color.rgb(255, 255, 255)} ); this.getWindow().setBackgroundDrawable(grad); } }

五、ShowSerView。java类的代码：
package com.cn.daming; import android.app.Activity; import android.graphics.Color; import android.graphics.drawable.GradientDrawable; import android.graphics.drawable.GradientDrawable.Orientation; import android.os.Bundle; import android.widget.TextView; public class ShowSerView extends Activity{ private TextView ser_text_view; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.show_ser_view); drawBackground(); ser_text_view = (TextView)findViewById(R.id.ser_text_view); MainActivity s_activity = (MainActivity)getIntent().getSerializableExtra(MainActivity.SER_KEY); ser_text_view.setText("You name is: " + s_activity.getS_name() + "\n"+ "You age is: " + s_activity.getS_number() +"\n"+ "You sex is: " + s_activity.getS_sex()); } public void drawBackground() { GradientDrawable grad = new GradientDrawable( Orientation.TL_BR, new int[] {Color.rgb(0, 0, 127), Color.rgb(0, 0, 255), Color.rgb(127, 0, 255), Color.rgb(127, 127, 255), Color.rgb(127, 255, 255), Color.rgb(255, 255, 255)} ); this.getWindow().setBackgroundDrawable(grad); } }
