使用Rxjava回调参数至Activity

定义一个继承PopupWindow的类

public class PopupWindows extends PopupWindow implements View.OnClickListener {    public PopupWindows (View parent, final Context context) {        super(context);        View view = View.inflate(context, R.layout.ppw_groups_join, null);    //设置PopupWindows 显示动画    setWidth(WindowManager.LayoutParams.MATCH_PARENT);        setHeight(WindowManager.LayoutParams.MATCH_PARENT);    setFocusable(true);        setOutsideTouchable(true);        setContentView(view);        showAtLocation(parent, Gravity.BOTTOM, 0, 0);        update();        view.findViewById(R.id.btn1).setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.btn1:                Observable.just(1).subscribe(MainActivity.action1);                break;        }        dismiss();    }}

在MainActivity定义Action1方法，需要先实例化

public class MainActivity extends Activity {    private Button btn1;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btn1=(Button) findViewById(R.id.btn1);        btn1.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                new PopupWindows(btn1, MainActivity.this);            }        });    }    public static Action1<int> action1 = new Action1<int>() {            @Override            public void call(int i) {                System.out.println(i);            }        };    }

使用接口回调参数至Activity

定义继承PopupWindow类

public class JoinPopupWindows extends PopupWindow implements View.OnClickListener{    public PopupWindows (View parent, final Context context) {        super(context);        View view = View.inflate(context, R.layout.ppw_groups_join, null);    //设置PopupWindows 显示动画    setWidth(WindowManager.LayoutParams.MATCH_PARENT);        setHeight(WindowManager.LayoutParams.MATCH_PARENT);    setFocusable(true);        setOutsideTouchable(true);        setContentView(view);        showAtLocation(parent, Gravity.BOTTOM, 0, 0);        update();        view.findViewById(R.id.btn1).setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()){            case R.id.btn1:                test.getTest(1);                break;        }        dismiss();    }    private ITest test;    public void setTest(ITest test) {        this.test = test;    }    public interface ITest {        void getTest(int i);    }}

在MainActivity继承ITest接口

public class MainActivity extends Activity implements ITest {    private Button btn1;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btn1=(Button) findViewById(R.id.btn1);        btn1.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                new PopupWindows(btn1, MainActivity.this).setTest(MainActivity.this);            }        });    }    @Override    public void getTest(int i) {        System.out.println(i);    }}
