如何在android中创建半透明的进度对话框

Question

我在谷歌上搜索了很多，甚至浏览了很多这个网站的问题，但我就是找不到解决我问题的方法。

我想创建一个像下面这样的进度对话框。但我不明白如何做到这一点。我已经尝试创建一个自定义的进度对话框，但。使用它，你只能修改内部旋转器的外观。在我的情况下，我想修改它的布局。我如何实现...？？？？

到目前为止，我已经尝试了以下方法...

public class nextclass extends Activity {

    Thread t;
    ProgressBar dia;

    private ProgressDialog progressDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        MainActivity.progressDialog.dismiss();
        setContentView(R.layout.nextclassview);
    //  requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);

        ((Button) findViewById(R.id.button1))
                .setOnClickListener(new OnClickListener() {

                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        // progressDialog = findViewById(R.id.progressBar1);

                        new AuthenticateUserTask().execute();
                    }
                });
    }

    private class AuthenticateUserTask extends AsyncTask<Void, Void, String> {

        @Override
        protected void onPreExecute() {
            // TODO Auto-generated method stub
            super.onPreExecute();

            progressDialog = ProgressDialog.show(
                    nextclass.this, "","Sucessful", true);
/*            progressDialog.setIndeterminate(true);

            progressDialog.setIndeterminateDrawable(getResources()
                    .getDrawable(R.layout.customspinner));
*/


            progressDialog = ProgressDialog.show(nextclass.this, "",
                    "Processing....", true);
            progressDialog.getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);

        }

        protected void onPostExecute(String s) {
            if (progressDialog.isShowing())
                progressDialog.dismiss();

            Intent my = new Intent(getApplicationContext(), CountTime.class);
            startActivity(my);

        }

        @Override
        protected String doInBackground(Void... params) {
            // TODO Auto-generated method stub
            try {
                Thread.sleep(2000);![custom spinner][2]
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return null;
        }
    }
}

有关如何创建自定义对话框的详细信息，请参阅此链接

WindowManager.LayoutParams WMLP = dialog.getWindow().getAttributes();


     WMLP.x = 100;   //x position
     WMLP.y = 100;   //y position

     dialog.getWindow().setAttributes(WMLP);

Edit2:使用代码创建对话框活动示例如下所示

public class DialogActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
        alertDialog.setTitle(" ");
        alertDialog.setMessage("");
        alertDialog.setIcon(R.drawable.icon);
        alertDialog.setButton("Accept", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {                
            }
        });
        alertDialog.setButton2("Deny", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        alertDialog.show();
    }
}

并且在android清单文件中

android:theme="@android:style/Theme.Translucent.NoTitleBar"

或

AlertDialog.Builder builder = new AlertDialog.Builder(
                    new ContextThemeWrapper(context, R.style.popup_theme));

在values文件夹中：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="back_color">#ffffffff</color>
<style name="popup_theme" parent="@android:style/Theme.Translucent.NoTitleBar">
    <item name="android:windowBackground">@color/back_color</item>
    <item name="android:colorBackground">@color/back_color</item>
</style>
