传递数据包bundle:
1、MainActivity.class:
findViewById(R.id.btnStartAty).setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this,TheAty.class);
Bundle b = new Bundle();
b.putString("name","Android");
b.putInt("age",2);
//b.putString("name1","Android");
//i.putExtras(b);
i.putExtra("data",b);
startActivity(i);
}
});
2、TheAty.class:
Intent i = getIntent();
//Bundle data = i.getExtras();
Bundle data = i.getBundleExtra("data");
tv =(TextView)findViewById(R.id.tv);
//name1不存在时默认w,存在时即为该值
tv.setText(String.format("name=%s,age=%d,name1=%s",data.getString("name"),data.getInt("age"),data.getString("name1","w")));
