难点的
AlertDialog.Builder dialog=new AlertDialog.Builder(TestActivity.this);
dialog.setTitle("This is Dialog");
dialog.setMessage("Somnus");
dialog.setCancelable(false);//可否取消
dialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
dialog.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
dialog.show();
ProgressDialog progresDialog=new ProgressDialog(TestActivity.this);
