copied!<p>you could make your method createBigWindow return the range object it just created</p> <pre><code>public static Out_of_range createBigWindow(Context context) { WindowManager windowManager = getWindowManager(context); int screenWidth = windowManager.getDefaultDisplay().getWidth(); int screenHeight = windowManager.getDefaultDisplay().getHeight(); if(bigWindow == null) { bigWindow = new Out_of_range(context); if(bigWindowParams == null) { bigWindowParams = new LayoutParams(); bigWindowParams.x = screenWidth / 2 - Out_of_range.viewWidth / 2; bigWindowParams.y = screenHeight / 2 - Out_of_range.viewHeight / 2; bigWindowParams.type = LayoutParams.TYPE_PHONE; bigWindowParams.format = PixelFormat.RGBA_8888; bigWindowParams.gravity = Gravity.LEFT | Gravity.TOP; bigWindowParams.width = Out_of_range.viewWidth; bigWindowParams.height = Out_of_range.viewHeight; } windowManager.addView(bigWindow, bigWindowParams); } return bigWindow; } </code></pre> <p>and then in your Out_of_range class create a method to receive the String you want to pass.</p> <p>Edit: </p> <pre><code>//in your Out_of_range class public void receiveStringValue(String value) { // do whatever you want } </code></pre> <p>and use it from your Main class after using the createBigWindow method:</p> <pre><code>Out_of_range range = MyWindowManager.createBigWindow(this); range.receiveStringValue(yourString); </code></pre> <p>I didn't try this out but I think it's worth trying.</p> <p>Edit2: </p> <p>Now that you've updated your Question it's clearer: try this:</p> <pre><code>public class Out_of_range extends LinearLayout { public static int viewWidth; public static int viewHeight; public Out_of_range(final Context context, String value) { super(context); // TODO Auto-generated constructor stub LayoutInflater.from(context).inflate(R.layout.out_of_range, this); View view = findViewById(R.id.big_window_layout); viewWidth = view.getLayoutParams().width; viewHeight = view.getLayoutParams().height; device = (TextView) findViewById(R.id.device); device.setText("device = " + value); Button back = (Button)findViewById(R.id.back); back.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub MyWindowManager.removeBigWindow(context); } }); } </code></pre> <p>And in your main, do something like this:</p> <pre><code>MyWindowManager.createBigWindow(getApplicationContext(), "your value here"); </code></pre>
