Hello, all!
For some reason, I need a dialog with "backgroundDimAmount=0".
But I found that if I start a "new" emulator, show my dialog will get
a black screen, and never come back even press BACK key. This will
happen every time I test on 1.6 donut version.
To solve it is to show any dialog without this setting first in my
activity or not, and then my dialog will work well.
I could not figure out why this is happened. Is that a bug?
Anyone could test using the following sample code.
public class mydialog extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//showDialog(0); // backgroundDimAmount default setting
showDialog(1); // backgroundDimAmount=0
}
@Override
protected Dialog onCreateDialog(int id) {
if(id==0)
{
Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Custom Dialog");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
return dialog;
}
else
{
Dialog dialog = new Dialog(this,R.style.Theme_doNotDim);
dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Custom Dialog with doNotDim");
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) dialog.findViewById(R.id.image);
image.setImageResource(R.drawable.icon);
return dialog;
}
}
}
