Avd showing old version of my application

Avd showing old version of my application - android

So i've make some change's in my app (it was about nesting layouts - My root layout, was linear layout,i wanted to change it to relative layout,i remember,it was something wrong with lines like xlmns:tools etc. I've copy those lines from my previous app,but then i've got an error that something is missing,so i google it,and somebody wrote about delete .idea and .gradle folders so i did,and now,my avd showing me "old content" just app before some changes. How i can solve it? The application that i've trying to make,it's just an typical clicker at case of my course. It's about to counting score of two teams.

Buttons Overlap

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

chronometer.stop();
resumeStopWatch.setClickable(false);
startStopWatch.setVisibility(View.VISIBLE);

}
});
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

Android - Add subview after animation

I'm trying to add a subview below another view after an animation. anyone have any idea what i'm doing wrong?
this.animate().translationY(newY - 170).setDuration(500).withEndAction(new Runnable() {
#Override
public void run() {
clearAnimation();
RouteBreakDownLayout routeBreakDownLayout = new RouteBreakDownLayout(mContext);
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, R.id.selected_route_layout);
routeBreakDownLayout.setLayoutParams(p);
addView(routeBreakDownLayout);
}
}).start();
Here is the XML for the layout. I have a scrollview embeded which will hold the content that needs to be animated in.

What goes wrong for you in your code-snippet?
Here's working example I came up with:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/containerRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="#+id/headerView"
android:background="#00FF00"
android:layout_width="match_parent"
android:layout_height="25dp"/>
<View
android:id="#+id/detailsView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="40dp"
android:clickable="true"
android:background="#FF0000"/>
</RelativeLayout>
And MainActivity is
package klogi.com.animationstestapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.RelativeLayout;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final View detailsView = findViewById(R.id.detailsView);
final View headerView = findViewById(R.id.headerView);
final RelativeLayout container = (RelativeLayout)findViewById(R.id.containerRelativeLayout);
container.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
detailsView.animate().translationY(-detailsView.getY()).setDuration(500).withEndAction(new Runnable() {
#Override
public void run() {
Button additionalButton = new Button(MainActivity.this);
additionalButton.setText("Additional button");
RelativeLayout.LayoutParams additionalButtonParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
additionalButtonParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
additionalButton.setLayoutParams(additionalButtonParams);
container.addView(additionalButton);
}
}).start();
headerView.animate().translationY(detailsView.getHeight()).setDuration(500).start();
}
});
}
}
It works just as expected.
Have you tried to add your control(RouteBreakDownLayout) without animation? Does it work? It can be something like control is actually adding, but it's out of the viewport, etc. - so far, I can just guessing.

An alert dialog with an image will appear once LinearLayout is clicked

here is my full code as you requested #mobie.. the Symptoms.java and the question.xml..dont matter the other code..just on the alert dialog that i asked.

Create Layout Like Below for Dialog Box : dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp" />
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="#+id/image"/>
<Button
android:id="#+id/dialogButtonOK"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Ok "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="#+id/image"
/>
</RelativeLayout>
Then, Where you want to place the Alert, Do like below
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Your Title");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Text");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.ic_launcher);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

How to place 2 buttons at the same position in my layout

I have My Table row like below in my xml layout:
<TableRow
android:layout_marginTop="10dp"
>
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="256dp"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/titlename"
android:layout_="#+id/playbtn"
android:layout_marginTop="4dp"
/>
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentBottom="true"
android:background="#drawable/play"
android:layout_marginBottom="3dp"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_toTopOf="#+id/playbtn"
android:layout_alignParentBottom="true"
android:background="#drawable/pause"
android:layout_marginBottom="3dp"/>
</TableRow>
and my output is as below,
my requirement is to show play pause buttons at the same position in my layout?
Could any one help?

Use FrameLayout and put one button over another
Like this
<FrameLayout ... >
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/play"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/pause"/>
</FrameLayout>
This will put Pause button over Play Button. Make the necessary button visible and invisible according to your need

Try using this layout. Use combination of LinearLayout and FrameLayout to achieve the desired result.
<TableRow
android:layout_marginTop="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weight="1"
android:layout_alignLeft="#+id/titlename"
android:layout_="#+id/playbtn"
android:layout_marginTop="4dp"
/>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<Button
android:id="#+id/playbtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/play"/>
<Button
android:id="#+id/pausebtn"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/pause"/>
</FrameLayout>
</LinearLayout>
</TableRow>

once Try this:
<TableRow
android:id="#+id/tableRow1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".8" />
<Button
android:id="#+id/play"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".2"
/>
</TableRow>
Main Activity
private boolean playing = false;
Button play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play=(Button) findViewById(R.id.play);
play.setBackgroundResource(R.drawable.pause);
play.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(playing){
playing = false;
play.setBackgroundResource(R.drawable.pause);
}
else {
playing = true;
play.setBackgroundResource(R.drawable.play);
}
}
});
}

Why can't you try merge?
Have a glance of this.

You don't need to create two buttons for it. You can do it with single. I have created a sample program. I find this to be a cleaner approach.
Layout for MainActivity
