1.Android 頁面間傳值（多個資料）先将資料封裝到Bundle類中，以鍵--值對儲存。在主Activity的OnClick事件中封裝Bundle。然後将Bundle對象放到Intent中。
package com.fruit;
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;
import android.widget.EditText;
public class IntantTextActivity extends Activity implements OnClickListener {
private EditText username, password;
private Button b1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
init();
}
private void init() {
b1 = (Button) findViewById(R.id.Button01);
b1.setOnClickListener(this);
username = (EditText) findViewById(R.id.username);
password = (EditText) findViewById(R.id.password);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.Button01:
String str_username = username.getText().toString();
String str_password = password.getText().toString();
Bundle b = new Bundle();
b.putString("username", str_username);
b.putString("password", str_password);
Intent intent = new Intent(IntantTextActivity.this, NextActivity.class);
intent.putExtras(b);
startActivity(intent);
break;
default:
break;
}
}
}
在第二個Activity中擷取Bundle中封裝的。通過Key值擷取Value值。
package com.fruit;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.*;
public class NextActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.next);
String str_username =getIntent().getExtras().getString("username");
String str_password = getIntent().getExtras().getString("password");
TextView user = (TextView)this.findViewById(R.id.user);
TextView pass = (TextView)this.findViewById(R.id.pass);
user.setText("使用者名:"+str_username);
pass.setText("密碼："+str_password);
}
}
首頁面配置檔案：main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:text="使用者名稱："
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<EditText
android:text=""
android:id="@+id/username"
android:layout_width="fill_parent"
android:layout_height="wrap_content"></EditText>
<TextView
android:text="使用者密碼："
android:id="@+id/TextView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
></TextView>
<EditText
android:text=""
android:id="@+id/password"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:password="true"
></EditText>
<Button
android:text="登陸"
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
</LinearLayout>
另外一個頁面配置檔案：<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView "
android:id="@+id/user"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<TextView
android:id="@+id/pass"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
></TextView>
</LinearLayout>
總配置檔案
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.fruit"
android:versionCode="1"
android:versionName="1.0" >
