Android 设置Dalog大小

注意：设置Dialog大小的代码，必须放在setContentView代码后面。否则设置无效。

1  Dialog processDialog=new Dialog(this);
2  TextView txt = new TextView(this);
3  txt.setText("hello");
4  processDialog.setContentView(txt);
5        
6  WindowManager.LayoutParams layoutParams=processDialog.getWindow().getAttributes();
7  layoutParams.height=LayoutParams.FILL_PARENT;
8  layoutParams.width=LayoutParams.FILL_PARENT;
9  processDialog.getWindow().setAttributes(layoutParams);
10
11  processDialog.getWindow().setBackgroundDrawableResource(R.drawable.sc_app_bg_pressed);
12  
13  processDialog.show();
