Android列表弹窗dialog（适合WiFi列表）

robotMsgDialog = new Dialog(this);
robotMsgDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
Window window = robotMsgDialog.getWindow();
window.setGravity(Gravity.CENTER);
window.setBackgroundDrawable(new BitmapDrawable());
robotMsgDialog.setCanceledOnTouchOutside(true);
robotMsgDialog.show();

两种方式设置dialog的宽高

1.设置宽

WindowManager.LayoutParams params = robotMsgDialog.getWindow().getAttributes();
params.width = (int) (this.getWindowManager().getDefaultDisplay().getWidth() * 0.7);
robotMsgDialog.getWindow().setAttributes(params);

2.设置宽高

WindowManager windowManager = (WindowManager) getApplicationContext().getSystemService(Context
        .WINDOW_SERVICE);
int width = (int) (windowManager.getDefaultDisplay().getWidth() * 0.7);
int height = (int) (windowManager.getDefaultDisplay().getHeight() * 0.3);
window.setLayout(width, height);

View dialogView = LayoutInflater.from(this).inflate(R.layout.dialog_robotmsg, null);
robotMsgDialog.addContentView(dialogView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams
        .WRAP_CONTENT));
dialog_ListView = (ListView) dialogView.findViewById(R.id.dialog_listView);
myAdapter = new RobotHistoryMsgAdapter(getApplicationContext());
myAdapter.setData(list);
dialog_ListView.setAdapter(myAdapter);
