问题 public class UnitConverterActivity extends Activity implements OnTouchListener { /** Called when the activity is first created. */ LinearLayout mLinearLayout; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mLinearLayout = new LinearLayout(this); ImageView i = new ImageView(this); i.setImageResource(R.drawable.mainmenu); //i.setAdjustViewBounds(false); i.setScaleType(ScaleType.FIT_XY); i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP

问题 The goal is to implement a Gallery whose adapter returns ListViews (in other words, vertically scrolling ListViews embedded in a horizontally scrolling Gallery). It sort of works after a bit of work, but when attempting to scroll horizontally, the ListView looks very jittery, like there is some stickiness to it being centered. I have not observed this kind of behavior with any other type of View embedded in a Gallery. Here is what I have tried: Initially, I found that the ListView squashed

问题 I'm making a Letter Drag n Drop game (kinda like Guess the Brand) where you have an image and you have to drag the letters into layouts to form the correct answer. At the top, I have Four layouts (layoutAnsw A to D), and in the bottom I have Four buttons (btnTop A to D) I have the OnTouchListener and OnDragListener working fine, except one single thing. What happens when I have more than one similar character (letter)? For example in this image: As you can see, I have to "A" letters that need

问题 I've set up an onTouch class to determine when one of my 40 buttons is pressed. The problem I am facing is determining which button was pressed. If I use: int ID = iv.getId(); When I click on button "widgetA1" I receive the following ID: 2131099684 I would like it to return the string ID "widgetA1" from:game.xml <ImageView android:layout_margin="1dip" android:id="@+id/widgetA1" android:src="@drawable/image" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>

问题 I am in a tricky situation, hope you can help me with it. I have few views (TextViews), horizontally placed one after another in a linear layout. When I press on textview1, drag my finger to any other textview and release touch, I want to be able to get the view(textview) on which the finger was lifted. I went over the TouchListener api, it says that every event starts with a ACTION_DOWN event action. Since other textviews won't fire that event, how can I get the reference to the textViews on

问题 Guys I'm having a strange problem: In a chat application I have a ListView and an Adapter to deal with it. If the user sends an image from gallery I will show a thumbnail on the bubble speech and add a onTouchListener to open this image on full screen.

So if I click on the last imageView it is showing the right image on the full screen, but all other's before are showing the same image. I reviewd the code a

问题 I am Using SwipeDismissTouchListener in my Code but it seams to work only for buttons , not for TextView, RelativeLayout etc. How to use it for other View Types? 回答1: Got the Solution :) It works for all views required they should have an onClickListener implemented. Buttons tend to have that by default :) 来源： https://stackoverflow.com/questions/20897288/swipetodismiss-works-only-on-buttons
