anyone can help me on how to resume ImageView.animation()? Based on my code bellow I can Pause animation but I can Resume.
pause = (Button) findViewById(R.id.pause);
pause.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
pause.setVisibility(View.INVISIBLE);
pause_release.setVisibility(View.VISIBLE);
pause_release.startAnimation(in);
//ant 1
walking_1.stop();
ant_play_1.animate().setListener(null);
ant_play_1.animate().cancel();
ant_play_1.setEnabled(false);
}
});
pause_release = (Button) findViewById(R.id.pause_release);
pause_release.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
pause.setVisibility(View.VISIBLE);
pause_release.startAnimation(out);
pause_release.setVisibility(View.GONE);
//ant 1
walking_1.start();
ant_play_1.animate().start();
ant_play_1.setEnabled(true);
}
});
How to modify my code to make it can Resume onClick?

I am trying to select items in recylerview. When I click an item, a checkbox appears on that item and it is highlighted. But the problem is that when I scroll, the item which is highlighted goes to its original color but the checkbox image remains as it should. Why the highlighted color is gone but the image remains after scrolling, I want the items to keep their state after scrolling.
public static List<Model> item = new ArrayList<Model>()
#Override
public void onBindViewHolder(#NonNull MyAdapter.MyViewHolder holder, int
position) {
holder.bind(item.get(position));
//
public class MyViewHolder extends RecyclerView.ViewHolder{
public MyViewHolder(#NonNull View itemView) {
super(itemView);
imageView = itemView.findViewById(R.id.check);
public void bind(Model model) {
if (model.isChecked()){
imageView.setVisibility(View.VISIBLE);
itemView.setBackgroundColor(Color.GRAY);
model.setChecked(true);
} else {
imageView.setVisibility(View.GONE);
itemView.setBackgroundColor(Color.TRANSPARENT);
model.setChecked(false);
}
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Model s = item.get(getAdapterPosition());
if (!selectList.contains(s)){
selectList.add(s);
model.setChecked(true);
} else {
selectList.remove(s);
model.setChecked(false);
}
notifyItemChanged(getAdapterPosition());
}
});
public class Model {
private boolean isChecked = false;
public boolean isChecked() {
return isChecked;
}
public void setChecked(boolean checked) {
isChecked = checked;
}
}
Don't manually change the design in the onclick listener, just update your model (as you are already doing: model.setchecked(...) depending on state)
Then call Adapter.notifyItemChanged(getAdapterPosition())
This will force the adapter to reload the item, calling onBindViewHolder, where the design should be updated properly
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Model s = item.get(getAdapterPosition());
if (!selectList.contains(s)){
selectList.add(s);
model.setChecked(true);
} else {
selectList.remove(s);
model.setChecked(false);
}
adapter.notifyItemChanged(getAdapterPosition())
}
In the above example, replace "adapter" with a reference to your recylerview adapter
I'm newbie in android and I'm trying to develop some applications. But last two weeks I've been stuck in this code. In short, I have two buttons in a layout. These buttons are Add and delete button. If I clicked the add button, add will be disabled and delete will be enabled. Or if I clicked the delete, delete will be disabled add will be enabled. I want to save state of these two buttons (which one is clicked) and get the last clicked state on create. But the problem is it's not working. When I open the app both buttons are show disable state. Or not saving either. Never working.
public class UserVideoInfoActivity2 extends AppCompatActivity {
SharedPreferences.Editor editor;
SharedPreferences preferences;
SharedPreferences.Editor editor2;
SharedPreferences preferences2;
Button buttonadd;
Button buttondelete;
private static final String ADD = "ADD_KEY";
private final static String DELETE = "DELETE_KEY";
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_video_info_layout_2);
buttonadd = (Button) findViewById(R.id.buttonaddlayout);
buttondelete = (Button) findViewById(R.id.buttondeletelayout);
preferences = getSharedPreferences(ADD, Context.MODE_PRIVATE);
preferences2 = getSharedPreferences(DELETE, Context.MODE_PRIVATE);
buttonadd.setEnabled(GetState());
buttondelete.setEnabled(GetState2());
buttonadd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
buttonadd.setEnabled(false);
buttondelete.setEnabled(true);
SaveState(buttonadd.isEnabled());
}
});
buttondelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
buttonadd.setEnabled(true);
buttondelete.setEnabled(false);
SaveState2(buttondelete.isEnabled());
}
});
}
private void SaveState(boolean isChecked) {
editor = preferences.edit();
editor.putBoolean(ADD, isChecked);
editor.commit();
}
private void SaveState2(boolean isChecked2) {
editor2 = preferences2.edit();
editor2.putBoolean(DELETE, isChecked2);
editor2.commit();
}
public boolean GetState() {
return preferences.getBoolean(ADD, false );
}
public boolean GetState2() {
return preferences2.getBoolean(DELETE, false);
}
}

i get my answer so silly mistake. search_medicine is null every time because cannot get string from edit text on action button click..
if (i == EditorInfo.IME_ACTION_SEARCH) {
search_medicne=edit_search_medicine.getText().toString();
getdata(search_medicne);
}
At first I have code like this
private void example(){
btnBack.setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View view) {
//some code
}
});
}
and then get code like this
private void example(){
btnBack.setOnClickListener(backListener);
}
View.OnClickListener backListener = new View.OnClickListener() {
#Override public void onClick(View view) {
//some code
}
};
That is simply "Extract -> Field" (Ctrl-Alt-F in Windows/Linux keymaps)
I found a tutorial and it looks like this:
package com.djrobotfreak.SVTest;
public class Tutorial2D extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(new Panel(this));
}
class Panel extends SurfaceView implements SurfaceHolder.Callback {
private TutorialThread _thread;
public Panel(Context context) {
super(context);
getHolder().addCallback(this);
_thread = new TutorialThread(getHolder(), this);
}
#Override
public void onDraw(Canvas canvas) {
Bitmap _scratch = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
canvas.drawColor(Color.BLACK);
canvas.drawBitmap(_scratch, 10, 10, null);
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
// TODO Auto-generated method stub
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
_thread.setRunning(true);
_thread.start();
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
// simply copied from sample application LunarLander:
// we have to tell thread to shut down & wait for it to finish, or else
// it might touch the Surface after we return and explode
boolean retry = true;
_thread.setRunning(false);
while (retry) {
try {
_thread.join();
retry = false;
} catch (InterruptedException e) {
// we will try it again and again...
}
}
}
}
class TutorialThread extends Thread {
private SurfaceHolder _surfaceHolder;
private Panel _panel;
private boolean _run = false;
public TutorialThread(SurfaceHolder surfaceHolder, Panel panel) {
_surfaceHolder = surfaceHolder;
_panel = panel;
}
public void setRunning(boolean run) {
_run = run;
}
#Override
public void run() {
Canvas c;
while (_run) {
c = null;
try {
c = _surfaceHolder.lockCanvas(null);
synchronized (_surfaceHolder) {
_panel.onDraw(c);
}
} finally {
// do this in a finally so that if an exception is thrown
// during the above, we don't leave the Surface in an
// inconsistent state
if (c != null) {
_surfaceHolder.unlockCanvasAndPost(c);
}
}
}
}
}
}
and it does not work, no matter what I do. I am trying to convert my code to surfaceview but I cant find any surfaceview programs that even work (besides the android-provided ones). Does anyone know what the error even is saying?
Here is my logcat info: http://shrib.com/oJB5Bxqs
If you get a ClassNotFoundException, you should check the Manifest file.
Click on the Application tab and look on the botton right side under "Attributes for".
If there is a red X mark under your Class Name, then click on the "Name" link and locate the correct class to load.
