更改code进度的位置 [英] Change position of progressbar in code

问题描述

我有我的$ C $创建Ç我的活动进度条。 这是code：

I have a progress bar which I create in code my activity. This is code:

progressDialog = new ProgressDialog(this); 
// Progress bar message.
String progressBarMessage = "Loading, please wait...";
progressDialog.getWindow().setGravity(Gravity.BOTTOM);

progressDialog.setCancelable(false);
progressDialog.setMessage(progressBarMessage);
// set the progress to be horizontal
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
// reset the bar to the default value of 0
progressDialog.setProgress(0);
// convert the text value to a integer
int maximum = 100;
// set the maximum value
progressDialog.setMax(maximum);
// display the progressbar
progressDialog.show();  

正如你所看到的位置，我的进度是底部。如何我可以改变位置，这进度，以我的网页3/4？我想移动的地位将中部和底部之间？也许我可以setMarginTop，但如何？

As you can see position my progressbar is bottom. How I can change position this progressbar to 3/4 of my page? I want to move that position will be between center and bottom? Maybe can I setMarginTop, but how?

推荐答案

尝试是这样的：

// ...
progressDialog.getWindow().setGravity(Gravity.CENTER);
WindowManager.LayoutParams wmlp = progressDialog.getWindow().getAttributes();
wmlp.y = height / 4;
progressDialog.getWindow().setAttributes(wmlp);
progressDialog.setCancelable(false);
// ...

其中，高度是 INT 值（屏幕的高度），你在<$ C初始化$ C>的onCreate 的方法是这样的：

Where height is an int value(the height of the screen) that you initialize in the onCreate method like this:

height = getResources().getDisplayMetrics().heightPixels;
