Question
I want to set Activity
in FrameLayout
. Here is my code:
FrameLayout fl = new FrameLayout(this);
fl = (FrameLayout ) findViewById(R.id.actioncontent);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View myview =LayoutInflater.from(this).inflate(R.layout.wallpaper, null);
fl.removeAllViews();
fl.addView(myview);
I am getting an error NullPointerException.

OTHER TIPS
You need to use inflator
insteed of LayoutInflater.from(this)
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View myview =LayoutInflater.from(this).inflate(R.layout.wallpaper, null);
fl.removeAllViews();
fl.addView(myview);
Replace above code with below
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View myview =inflater .inflate(R.layout.wallpaper, null);
fl.removeAllViews();
fl.addView(myview);
You didn't state what 'this' was, or where the NPE is happening - but it could be that 'this' presents the wrong context.
Try using your activity name instead? For instance, MainActivity.this
Also, as was stated below me, replace from View myview =LayoutInflater.from(this).inflate
to View myview = inflater.inflate
