Intent数据传递两种常见方式

一、方法1：

//发送
Intent intent = new Intent(xxx.this, xxx.class);

Bundle bundle = new Bundle();
bundle.putString( "tag1", "aaa");
bundle.putInt("tag2", 22);
intent.putExtras( bundle );

startActivity( intent );

//接收
Intent intent = getIntent();

Bundle bundle = intent.getExtras();
String s = bundle.getString( "tag1" );
int i = bundle.getInt( "tag2" );

二、方法2：
//发送
Intent intent = new Intent(xxx.this, xxx.class);

intent.putExtra( "tag1", "aaa" );
intent.putExtra( "tag2", 2 );

startActivity( intent );

//接收
Intent intent = getIntent();

String s = intent.getStringExtra( "tag1" );
int i = intent.getIntExtra( "tag2" );
