MainActivity：点击一个Button会跳转到另一个NextActivity
package com.example;import java.util.ArrayList;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button button = (Button) findViewById(R.id.but1); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent(MainActivity.this, NextActivity.class); /* * 第二种 * Intent intent2=new Intent(); * intent2.setClass(MainActivity.this, NextActivity.class); *第三种： * Intent intent3 =new Intent("com.example.NextActivity"); *注意：此方法一定要在Manifest清单文件中配置intent-filter标签中配置action属性 * * 等价于： * Intent intent3 =new Intent("com.example.NextActivity"); * intent3.setAction(com.example.NextActivity"); * * 最后不要忘记有个：startActivity（intent）方法哦！ */ intent.putExtra("name", "zhangsan"); intent.putExtra("age", 20); ArrayList<String> arrayList = new ArrayList<String>(); arrayList.add("1"); arrayList.add("2"); arrayList.add("4"); intent.putStringArrayListExtra("unknow", arrayList); startActivity(intent); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; }}
AndroidManifest文件：
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.example.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".NextActivity"> <intent-filter > <action android: name="com.example.NextActivity"/> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> </application></manifest>
在NextActivity中得到由MainActivity传过来的数据：
package com.example;
import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
public class NextActivity extends Activity {
private final String TAG = "NextActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_next);
Intent intent = getIntent();
String name = intent.getStringExtra("name");
Log.i(TAG, "--name-->>" + name);
int age = intent.getIntExtra("age", 0);
Log.i(TAG, "--age-->>" + age);
ArrayList<String> arrayList = intent.getStringArrayListExtra("unknow");
for (String s : arrayList) {
Log.i(TAG, s);
}
}
}
