How to add more views, buttons to activity

I have a problem. I make a class DrawingView with button etc. and on activity i call it
public class PaintActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
DrawingView view=new DrawingView(this);
setContentView(view);
addContentView(view.btnEraseAll, view.params);
}
and here is my configuration
class DrawingView extends View {
private Paint brush = new Paint();
private Path path = new Path();
public Button btnEraseAll, btnAccept, btnBack;
public ViewGroup.LayoutParams params;
public DrawingView(Context context) {
super(context);
brush.setAntiAlias(true);
brush.setColor(Color.BLACK);
brush.setStyle(Paint.Style.STROKE);
brush.setStrokeJoin(Paint.Join.ROUND);
brush.setStrokeWidth(22f);
btnEraseAll = new Button(context);
btnEraseAll.setText("Clear");
btnAccept = new Button(context);
btnAccept.setText("Accept");
btnBack = new Button(context);
btnBack.setText("Back");
params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
btnEraseAll.setLayoutParams(params);
btnAccept.setLayoutParams(params);
btnBack.setLayoutParams(params);
btnEraseAll.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
path.reset();
postInvalidate();
}
});
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawPath(path, brush);
}
public boolean onTouchEvent(MotionEvent event) {
float pointX = event.getX();
float pointY = event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
path.moveTo(pointX, pointY);
return true;
case MotionEvent.ACTION_MOVE:
path.lineTo(pointX, pointY);
break;
default:
return false;
}
postInvalidate();
return false;
}
}
but how i can add more buttons(i have 3) to activity main?

I refactored some of your code to make it easier to undertand.
I also extracted the buttons in .xml instead of creating them programmatically because it is much easier. I also extracted the DrawingView to a separate class. I also tested it so it works for sure.
public class PaintActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_paint);
final DrawingView drawingView = (DrawingView) findViewById(R.id.drawing_canvas);
View clearBtn = findViewById(R.id.btn_clear);
clearBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
drawingView.reset();
}
});
}
}
class DrawingView extends View {
private Paint brush = new Paint();
private Path path = new Path();
public DrawingView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
brush.setAntiAlias(true);
brush.setColor(Color.BLACK);
brush.setStyle(Paint.Style.STROKE);
brush.setStrokeJoin(Paint.Join.ROUND);
brush.setStrokeWidth(22f);
}
public void reset() {
path.reset();
postInvalidate();
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawPath(path, brush);
}
public boolean onTouchEvent(MotionEvent event) {
float pointX = event.getX();
float pointY = event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
path.moveTo(pointX, pointY);
return true;
case MotionEvent.ACTION_MOVE:
path.lineTo(pointX, pointY);
break;
default:
return false;
}
postInvalidate();
return false;
}
}

How to trigger Wallpaperservice.enigine class using alarm manager. (I don't want to use RTC_Wakeup)

I am developing a wallpaper app. Which create a folder in external storage if that folder don't exist. User set time interval. Then app will set wallpaper (if not empty) from that folder in interval provided by user.
File dir= new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/"+"imagesWallpaper");
if(!dir.isDirectory())
dir.mkdirs();
It is not creating folder i exteral memory don,t know why

you have to use write external storage permission. thats why its not creating your directory.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
add this along with your Alarm and Wallpaper persmissions in your manifest

I tried changing the gravity and it does not seem to work, and I could not find anything on the internet to fix this issue. The mediaContoller is anchored to R.id.videoView. I don't know how this works in other apps like play books.

I faced the same issue recently, I didn't find any good way to solve it, but that workaround :
First get the navigation_bar_height :
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
mNavigationBarSize = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, getResources().getDimension(resourceId), resources.getDisplayMetrics());
}
Then, you can add a listener to your mediaController, something like that (mRelativeLayout is the parent of my videoview) :
mMediaController.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
#Override
public void onViewAttachedToWindow(View view) {
((FrameLayout.LayoutParams) mRelativeLayout.getLayoutParams()).bottomMargin = mNavigationBarSize;
mRelativeLayout.requestLayout();
}
#Override
public void onViewDetachedFromWindow(View view) {
hideSystemUI();
((FrameLayout.LayoutParams) mRelativeLayout.getLayoutParams()).bottomMargin = 0;
mRelativeLayout.requestLayout();
}
});
I hope it will help you
Edit : if your activity have a "white theme", you'll see a little graphical glitch when switching, you may have to add : <item name="android:windowBackground">#null</item> in the theme of this activity (or do it programmaticly)

I got the solution by setting Gravity and Margins.
Layout File
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/black">
<VideoView
android:id="#+id/videoSurface"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"/>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/my_spinner"
android:layout_gravity="center"/>
</FrameLayout>
Now, on OnCreate() set MediaController layout and assign the same using setLayoutParams().
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_sample_video);
ColorDrawable drawable = new ColorDrawable(Color.argb(100,0,0,0));
getSupportActionBar().setBackgroundDrawable(drawable);
getSupportActionBar().setTitle("Big Bunny");
spinner = (ProgressBar)findViewById(R.id.my_spinner);
dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
lpp = new FrameLayout.LayoutParams(dm.widthPixels, 170);
lpp.gravity= Gravity.BOTTOM;
lpp.setMargins(0,0,0,100);
video = (VideoView)findViewById(R.id.videoSurface);
video.setVideoPath("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");
video.setMediaController(mediaController = new MediaController(this){
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK ) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
return true;
} else if (event.getAction() == KeyEvent.ACTION_UP) {
((Activity) getContext()).onBackPressed();
return true;
}
}
return super.dispatchKeyEvent(event);
}
});
hideSystemUI();
mediaController.setLayoutParams(lpp);
mediaController.setAlpha(0.5f);
video.start();
video.setOnCompletionListener(this);
video.setOnInfoListener(this);
}
If you want, you can also handle orientation changes using below code.
#Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
{
getWindowManager().getDefaultDisplay().getMetrics(dm);
lpp = new FrameLayout.LayoutParams(dm.widthPixels, 170);
//lpp.gravity= Gravity.BOTTOM;
//lpp.setMargins(0,0,0,100);
mediaController.setLayoutParams(lpp);
//Toast.makeText(getApplicationContext(),"Landscape",Toast.LENGTH_LONG).show();
}
else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
{
getWindowManager().getDefaultDisplay().getMetrics(dm);
lpp = new FrameLayout.LayoutParams(dm.widthPixels, 170);
lpp.gravity= Gravity.BOTTOM;
lpp.setMargins(0,0,0,100);
mediaController.setLayoutParams(lpp);
//Toast.makeText(getApplicationContext(),"Portrait",Toast.LENGTH_LONG).show();
}
}

Chat-Heads-Like Popup window

I searched the web for how to make a popup window like Facebook's Chat Heads.
I found the following code: http://www.piwai.info/chatheads-basics/
public class ChatHeadService extends Service {
private WindowManager windowManager;
private ImageView chatHead;
#Override public IBinder onBind(Intent intent) {
// Not used
return null;
}
#Override public void onCreate() {
super.onCreate();
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
chatHead = new ImageView(this);
chatHead.setImageResource(R.drawable.ic_launcher);
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 100;
windowManager.addView(chatHead, params);
}
#Override
public void onDestroy() {
super.onDestroy();
if (chatHead != null) windowManager.removeView(chatHead);
}
}
In my Main Activity:
startService(new Intent(context, ChatHeadService.class));
And I use the permission:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
But I don't get the popup notification. Not even his icon.
Can you help me an say what's wrong?
Thanks.

Check if you have added your service to AndroidManifest.xml
<service android:name=".ChatHeadService" ></service>

Try Copy/Paste this in your project or you can create a new project and copy/paste this into it(with the required imports).
