I am working on an android project, and for that I have a human model image:
I would like to zoom right in, so that you can only see one human model e.g. the middle one to start with, then have 2 arrows on either side of the image, and click left arrow to see the left human model, and right to see the right human model.
This is my attempt, but doesn't work

i want to set zoom controls on TextView and ImageView. where, when zoom in pressed then all the textview and imageview are being zoomed in, and when zoom out pressed all the textview and imageview are being zoomed out with the function of scrollable left & right.
or, is it possible pinch to zoom only in imageview?
my try is below, but not worked perfectly.

I made a stopwatch using chronometer with four buttons but when i use the visibility modes to make stop and pause button appear they overlap.... Pls explain why...Below is the code.....
Assume the layout file with buttons in relative layout...
public class StopWatchFragment extends Fragment {
Chronometer chronometer;
Button startStopWatch;
Button stopStopWatch;
Button resetStopWatch;
Button pauseStopWatch;
Button resumeStopWatch;
private long lastPause;
//RelativeLayout relativeLayout;
private int check = 0;
public StopWatchFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.stopwatch_layout,container,false);
chronometer = (Chronometer) rootView.findViewById(R.id.stopwatch);
startStopWatch = (Button) rootView.findViewById(R.id.startStopWatch);
stopStopWatch = (Button) rootView.findViewById(R.id.stopStopWatch);
resetStopWatch = (Button) rootView.findViewById(R.id.resetStopWatch);
pauseStopWatch = (Button) rootView.findViewById(R.id.pauseStopWatch);
resumeStopWatch = (Button) rootView.findViewById(R.id.resumeStopWatch);
relativeLayout = (RelativeLayout) rootView.findViewById(R.id.parentRelativeLayout);
pauseStopWatch.setVisibility(View.GONE);
//final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(relativeLayout.getLayoutParams());
startStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.start();
startStopWatch.setVisibility(View.GONE);
pauseStopWatch.setVisibility(View.VISIBLE);
if(check == 1){
resumeStopWatch.setClickable(true);
}
else{
resumeStopWatch.setClickable(false);
}
//params.setMargins(16,16,16,16);
//pauseStopWatch.setLayoutParams(params);
}
});
pauseStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
check = 1;
lastPause = SystemClock.elapsedRealtime();
chronometer.stop();
}
});
resumeStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(chronometer.getBase() + SystemClock.elapsedRealtime() - lastPause);
chronometer.start();
resumeStopWatch.setClickable(false);
}
});
stopStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.stop();
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
resumeStopWatch.setClickable(false);
}
});
resetStopWatch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.stop();
resumeStopWatch.setClickable(false);
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
}
});
return rootView;
}
}

This is the way buttons work when click on start button
You are hiding the button, but you are still listening with the OnClickListener. Try adding:
pauseStopWatch.setOnClickListener(null);
Then, when you make your button visible:
pauseStopWatch.setOnClickListener(whatever);
Try this layout

In the above, the pause button will be set to Gone. You make it visible later when user clicks start button

First wrap everything inside a ScrollView
and now place your button and a textview inside a LinearLayout like this
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true">
<Button
android:text="Descrizione"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/descrizione" />
<TextView

Now in button click action set your text to the textView and don't forget to change its visibility to visible. Finally scroll to the textView with scrollView.fullScroll(View.FOCUS_DOWN)
-----For Auto Scrolling webview click on Toggle Button ----
public class MainActivity extends AppCompatActivity {
TimerTask mTimerTask;
final Handler handler = new Handler();
Timer t = new Timer();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ToggleButton toggleButton = (ToggleButton)findViewById(R.id.toggleButton);
final WebView webView = (WebView) findViewById(R.id.webView);
webView.loadUrl("https://en.wikipedia.org/wiki/Blog");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
toggleButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean ischecked) {
if (ischecked) {
Toast.makeText(MainActivity.this,"Start AutoScrolling", Toast.LENGTH_SHORT).show();
doTimerTask(); }
else{
stopTask();
Toast.makeText(MainActivity.this,"Stop AutoScrolling", Toast.LENGTH_SHORT).show();
}
}
private void stopTask() {
mTimerTask.cancel();
}
private void doTimerTask() {
mTimerTask = new TimerTask() {
public void run() {
handler.post(new Runnable() {
public void run() {
webView.post(new Runnable() {
public void run() {
if (webView.getContentHeight() * webView.getScale() >= webView.getScrollY()) {
webView.scrollBy(0, 5);
}
}
});
}
});
}};
// public void schedule (TimerTask task, long delay, long period)
t.schedule(mTimerTask, 0, 500);
}
});
}
}

LoginActivity.class
private LinearLayout lnrLoginView;
#Override
public void onCreate(Bundle savedInstanceState ) {
super.onCreate(savedInstanceState);
setContentView(R.layout.before_login_screen);
animloginButton = (Button) findViewById(R.id.animloginButton);

Try to use ObjectAnimator.onFloat instead.
animloginButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(lnrLoginView.getTag() instanceof Animator){
((Animator)lnrLoginView.getTag()).cancel();
}
ObjectAnimator translateY = ObjectAnimator
.ofFloat(target, "translationY", -transY)
.setDuration(1000)
;
translateY.setStartDelay(10);
translateY.setTarget(lnrLoginView);
translateY.setInterpolator(new BounceInterpolator());
translateY.start();
animloginButton.setVisibility(View.INVISIBLE);
}
private int getDisplayHeight() {
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
return metrics.widthPixels;
}
});
Use a animation listener to malipulate your views before and after the animation.
translation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
//Disable the views.
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
//Enable the views
}
});
