当我使用触摸侦听器。里面的触摸监听我所说的方法。该方法的参数要活动和视图。当我在服务中使用getApplicationContext()它显示Wrong 1st argument type. Found: 'android.content.Context', required: 'android.app.Activity'
我下面的代码给出
my service.Java
chatHead.setOnTouchListener(new View.OnTouchListener() {
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
initialX = params.x;
initialY = params.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
startX = event.getX();
startY = event.getY();
return false;
case MotionEvent.ACTION_UP:
float endX = event.getX();
float endY = event.getY();
if (isAClick(startX, endX, startY, endY)) {
Log.d("LockView", "clicked2");
CircularAnim.fullActivity(getApplicationContext(), v)
.colorOrImageRes(R.color.color1)
.go(new CircularAnim.OnAnimationEndListener() {
@Override
public void onAnimationEnd() {
startActivity(new Intent(getApplicationContext(), BrowserActivity.class));
}
});
}
return true;
case MotionEvent.ACTION_MOVE:
params.x = initialX
+ (int) (event.getRawX() - initialTouchX);
params.y = initialY
+ (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(chatHead, params);
return false;
}
return true;
}
});
windowManager.addView(chatHead, params);
private boolean isAClick(float startX, float endX, float startY, float endY) {
float differenceX = Math.abs(startX - endX);
float differenceY = Math.abs(startY - endY);
if (differenceX > CLICK_ACTION_THRESHHOLD/* =5 */ || differenceY > CLICK_ACTION_THRESHHOLD) {
return false;
}
return true;
}
circular A你们.Java
public static FullActivityBuilder fullActivity(Activity activity, View triggerView) {
return new FullActivityBuilder(activity, triggerView);
}
public static void init(long perfectMills, long fullActivityPerfectMills, int colorOrImageRes) {
sPerfectMills = perfectMills;
sFullActivityPerfectMills = fullActivityPerfectMills;
sColorOrImageRes = colorOrImageRes;
}
该getApplicationContext()越来越在CircularAnim.fullActivity(MainActivity.this, view)但它不是在CircularAnim.fullActivity
如何解决getApplicationContext在CircularAnim.fullActivity(getApplicationContext(), v)问题
请帮我。

做这种方式...
public Context mContext;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
mContext = getApplicationContext();
} }
getApplicationContext（）的相关应用程序，而不是活动的，因此，你应该使用activityname.this或getBaseContext（）和您尝试使用应用程序上下文执行UI线程操作，活动UI相关操作应和使用活动上下文执行，而不是应用程序上下文
如果你需要的是从服务访问活动的背景下，另一件事你可以尝试通过活动方面的服务的构造函数。例如：
活动
public class BT_Client extends Activity{
private BtService mBTService;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
mBtService = new BtService(this, ...);
}
}
服务
public class BtService {
Context myActivityContext;
public BtService(Context context, ...) {
myActivityContext = context;
...
}
}
