Android(安卓)数据传递-通过静态变量传递数据

使用Intent可以很方便在不同的Activity之间传递数据，这个也是官方推荐的方式，但是也有一定的局限性，就是 Intent无法传递不能序列化的对象，例如（图片）。我们可以使用静态变量来解决这个问题

Ø案例一

package com.android.myintent;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.Button;public class Main extends Activity {/** Called when the activity is first created. */private Button button;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);button = (Button) this.findViewById(R.id.button);button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stub// 声明一个意图Intent intent = new Intent();intent.setClass(Main.this, OtherActivity.class);OtherActivity.age = 23;OtherActivity.name = "jack";startActivity(intent);}});}}

package com.android.myintent;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class OtherActivity extends Activity {private TextView textView;public static String name;public static int age;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.other);textView = (TextView)this.findViewById(R.id.msg);textView.setText("-name->>"+name+"\n"+"-age-->>"+age);}}
