Android 2.0 中调用 subActivity 时数据传送
2010-03-25 17:03:00 来源:WEB开发网Android---2.0与之前的1.6中的数据传送方式不太一样。最大区别:
1.6
Java代码
protected void onActivityResult(int requestCode, int resultCode, String data, Bundle extras)
{ /* Place out code to react on Activity-Result here. */
super.onActivityResult(requestCode, resultCode, data, extras);
}
MySecondActivity.this.setResult(1, keyword);
protected void onActivityResult(int requestCode, int resultCode, String data, Bundle extras)
{ /* Place out code to react on Activity-Result here. */
super.onActivityResult(requestCode, resultCode, data, extras);
}
MySecondActivity.this.setResult(1, keyword);
2.0
Java代码
protected void onActivityResult(int requestCode, int resultCode, Intent i)
{
super.onActivityResult(requestCode, resultCode, i);
}
protected void onActivityResult(int requestCode, int resultCode, Intent i)
{
super.onActivityResult(requestCode, resultCode, i);
}
应该说2.0中将data以及extras都放进了intent,封装的更好了.使用中注意即可.
Java代码
//传送时
Intent data = new Intent();
data.putExtra("Data", search.getText().toString());
subActivityWithResult.this.getIntent().putExtra("Data",
search.getText().toString());
subActivityWithResult.this.setResult(SUCCESS_RETURN_CODE, data);
subActivityWithResult.this.finish();
//接收时
protected void onActivityResult(int requestCode, int resultCode, Intent i)
{
super.onActivityResult(requestCode, resultCode, i);
if(requestCode==SUB_ACTIVITY_REQUEST_CODE)
{
data=i.getExtras().getString("Data"));
}
}
