问题 I am working on an app in which I have some edit texts and background image. I wrote something in that edit text, I want to save whole current screen as an image, so that I can send it via email. I got a solution using ASL(android screenshot library) but for this I have to start native service on my device every time when I reboot it.

问题 I'm getting screen size using this code: getWindowManager().getDefaultDisplay().getRealSize(size); sw = size.x; sh = size.y; I'm using it for specifying DialogFragment width and height: @Override public void onResume() { super.onResume(); int sw = Util.getInstance().getScreenWidth(getActivity()); int sh = Util.getInstance().getScreenHeight(getActivity()); getDialog().getWindow().setLayout((int)(sw*0.6), (int)(sh*0.6)); } *I need to specify the width and height of the dialog in onResume.

问题 Currently I'm using paintObject.measureText(textCopy.substring(0,i)) while iterating through a copy of the TextView's text. For example, measureText("abc".substring(0,1)) will give me the relative x coordinates of 'b'. The y coordinate I get from layout.getLineTop() . This is working but not accurate for x coordinates for non-monospaced fonts. I can calibrate a little, but on each device it works differently.

问题 I am going to develop new application in Android. This application should only work in portrait (even for tablet). Also the UI and layout design should be similar on phones and tablet. We can't change the layout design for tablet as it has huge area to use. We have to stretch all the images to match phones. We can use nine patch. But I am little bit confused of using images in multiple drawables. As per my analysis (may be wrong.. : ) ) the screens are divided into density and sizes. We can
