隱式傳遞數據通常使用intent.setData(Uri.parse("ldw:canshu"))攜帶參數。

顯示傳遞數據有2種攜帶數據的方法一種是intent，另一種是bundle攜帶參數。

intent方式：

intent方式攜帶參數：

    	//數據封裝到intent中,前面是參數名后面是參數的值name-value的形式    	intent.putExtra("name1", "A");    	intent.putExtra("name2", "B");intent方式獲取參數：
	//從intent對象中取出封裝好的數據	String name1 = intent.getStringExtra("name1");	String name2 = intent.getStringExtra("name2");bundle方式：
bundle方式攜帶參數：
    	//把數據封裝到bundle對象中,bundle是以keyvalue的形式傳遞數據    	Bundle bundle = new Bundle();    	bundle.putString("name1", "A");    	bundle.putString("name2", "B");    	//把bundle對象封裝到intent對象中    	intent.putExtras(bundle);bundle方式獲取參數：
	Bundle bundle = intent.getExtras();	String name1 = bundle.getString("name1");	String name2 = bundle.getString("name2");
顯示跳轉需要配置清單文件，這里面我們準備跳轉到SecondActivity
<activity android:name="com.ldw.lifecycle.SecondActivity"/>第一個activity的代碼如下：
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity"     android:orientation="vertical"    >    <TextView         android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="這個是測算"        />    <EditText         android:id="@+id/name1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="A"        />    <EditText         android:id="@+id/name2"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="B"        />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="跳轉"         android:onClick="click"        /></LinearLayout>MainActivity.java
package com.ldw.lifecycle;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.EditText;public class MainActivity extends Activity {    @Override    PRotected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        System.out.println("第一個onCreate方法調用");    }    public void click(View v){    	    	Intent intent = new Intent(this,SecondActivity.class);    	//數據封裝到intent中,前面是參數名后面是參數的值    	intent.putExtra("name1", "A");    	intent.putExtra("name2", "B");    	startActivity(intent);    } }第二個activity的代碼如下：activity_second.xml
<?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:id="@+id/res"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="跳轉到第一個activity"         android:onClick="click1"        /></LinearLayout>SecondActivity.java
package com.ldw.lifecycle;import java.util.Random;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.TextView;public class SecondActivity extends Activity {	@Override	protected void onCreate(Bundle savedInstanceState){		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_second);				Intent intent = getIntent();		//從intent對象中取出封裝好的數據		String name1 = intent.getStringExtra("name1");		String name2 = intent.getStringExtra("name2");		Random rd = new Random();		int result = rd.nextInt(100);				TextView res = (TextView) findViewById(R.id.res);		res.setText(name1 + "和" + name2 + "的測試結果是" +result);	}	}使用bundle傳遞數據的時候，代碼如下，布局文件不需要更改
MainActivity.java
package com.ldw.lifecycle;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        System.out.println("第一個onCreate方法調用");    }    public void click(View v){    	    	Intent intent = new Intent(this,SecondActivity.class);    	//數據封裝到intent中,前面是參數名后面是參數的值name-value的形式    	//intent.putExtra("name1", "A");    	//intent.putExtra("name2", "B");    	    	//把數據封裝到bundle對象中,bundle是以keyvalue的形式傳遞數據    	Bundle bundle = new Bundle();    	bundle.putString("name1", "A");    	bundle.putString("name2", "B");    	//把bundle對象封裝到intent對象中    	intent.putExtras(bundle);    	    	startActivity(intent);    } }SecondActivity.java
package com.ldw.lifecycle;import java.util.Random;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TextView;public class SecondActivity extends Activity {	@Override	protected void onCreate(Bundle savedInstanceState){		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_second);				Intent intent = getIntent();		//從intent對象中取出封裝好的數據		//String name1 = intent.getStringExtra("name1");		//String name2 = intent.getStringExtra("name2");				Bundle bundle = intent.getExtras();		String name1 = bundle.getString("name1");		String name2 = bundle.getString("name2");		Random rd = new Random();		int result = rd.nextInt(100);				TextView res = (TextView) findViewById(R.id.res);		res.setText(name1 + "和" + name2 + "的測試結果是" +result);	}	}
