我正在尝试将对象传递给某个活动。我知道有一百万个问题就像这个问题一样,我确信这里的某个地方是一个答案,但我似乎无法找到它而我无法让它发挥作用。我一直收到错误消息(起初我不断收到In [1155]: np.save('test.npy',np.array([1,2]))
In [1156]: ls -l test.npy
-rw-rw-r-- 1 paul paul 88 Jun 30 17:08 test.npy
In [1157]: np.save('test.npy',np.arange(1000))
In [1158]: ls -l test.npy
-rw-rw-r-- 1 paul paul 4080 Jun 30 17:08 test.npy
,而不是NullPointerException
。)
这是我试图传递它的方法:
java.lang.RuntimeException: Parcelable encountered IOException writing serializable object
到这里:
public void createView(){
Intent mIntent = new Intent(getMain(), ButtonLayout.class);
mIntent.putExtra("controller", getController());
getMain().startActivity(mIntent);
}
我的Controller类实现了public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.button_panel);
this.controller = (Controller) getIntent().getSerializableExtra("controller");
calculate = (Button) findViewById(R.id.calc);
calculate.setOnClickListener(new WorkAppOnClickListener(this.controller));
}
:
Serializable
我尝试过import java.io.Serializable;
public class Controller implements Serializable{
private Calculate currentActivity;
private ButtonLayoutModel buttonLayout;
AvModel av;
public void setCurrentActivity(Calculate active){
this.currentActivity = active;
}
public Calculate getCurrentActivity(){
return this.currentActivity;
}
public void setAv(AvModel av){
this.av = av;
}
public AvModel getAv(){
return this.av;
}
public void setButtonLayout(ButtonLayoutModel bl){
this.buttonLayout = bl;
}
public ButtonLayoutModel getButtonLayout(){
return this.buttonLayout;
}
}
而不是控制器,我尝试Serializable
,但这似乎没有帮助;(

已经回答过了。 Passing JSONObject into another activity
“您可以简单地将整个JSONObject作为字符串。这样的事情:
i.putString(“product”,jsonObj.toString);
然后在MovieProductActivity中你可以
JSONObject jsonObj = new JSONObject(getIntent()。getStringExtra(“product”)); “
