IntentInjector
做app的时候,经常遇到这样的需求:将数据放置在Intent中,再通过startActivity方法传给下一个Activity。常用写法如下所示:
Intent intent = new Intent(this, StickyTabActivity.class);
intent.putExtra("string", "sdsd");
intent.putExtra("int", 101);
intent.putExtra("boolean", true);
intent.putExtra("object", DummyContent.ITEMS.get(0));
startActivity(intent);
在StickyTabActivity中,通过如下代码取出数据:
mBoolean = getIntent().getBooleanExtra("boolean", true);
如果使用IntentInjector
,在StickyTabActivity中,可以这样写:
@InjectIntent("object")
public DummyContent.DummyItem mData;
@InjectIntent("int")
private Integer mI;
@InjectIntent("boolean")
private boolean bool;
再调用:
IntentInjector.inject(this);
此后,@InjectIntent标注的成员变量即可获得传递的数据。成员变量可为private。@InjectIntent支持标注方法,如下所示:
@InjectIntent("string")
public void testInject(String data) {
Log.d(TAG, "testInject: " + data);
}
要求方法为public,仅有一个参数。
