如何使定制对话框中心在android系统？ [英] How to align custom dialog centre in android ?

问题描述

我工作的地方我想显示对话框是屏幕尺寸的应用。所以我用code below.I通过了这里的解决方案<一个href=\"http://stackoverflow.com/questions/10432184/alert-message-is-not-displaying-in-alert-dialog-box\">Alert消息没有在警告对话框中显示？

I am working on the application where i wanted to display the dialog to be screen size. So i used code below.I got the solution through here Alert message is not displaying in alert dialog box?

 AlertDialog.Builder builder = new AlertDialog.Builder(this);
    TextView title = new TextView(this);
    title.setText("DM2");
    title.setBackgroundColor(Color.DKGRAY);
    title.setPadding(10, 10, 10, 10);
    title.setGravity(Gravity.CENTER);
    title.setTextColor(Color.WHITE);
    title.setTextSize(20);


    TextView text = new TextView(this);  
    text.setText("Hello This text");  
    text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    text.setTextSize(20);        
    text.setGravity(Gravity.CENTER);

    //Creates a linearlayout layout and sets it with initial params
    LinearLayout ll = new LinearLayout(this);
    ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    ll.setGravity(Gravity.CENTER);
    ll.addView(text); 
    builder.setCustomTitle(title);
    builder.setPositiveButton(
            "Ok", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.dismiss();
                }
            }); 

    Dialog d = builder.setView(ll).create();
    //Fills up the entire Screen
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    lp.copyFrom(d.getWindow().getAttributes());
    lp.width = WindowManager.LayoutParams.FILL_PARENT;
    lp.height = WindowManager.LayoutParams.FILL_PARENT;
    d.show();
    d.getWindow().setAttributes(lp); 

但我想对话将出现在居中对齐。现在是在窗口顶部显示。
我试着用lp.garvity = Gravity.center，但没有奏效。
而如果设备方向的变化，我需要preSS确定按钮更多的时间来关闭对话框。如何解决这一问题？

But I want dialog to be appeared in center aligned. Now it is display in top of the window. I tried with lp.garvity = Gravity.center, but didn't work. and If the device orientation changes, i need to press ok button more time to close the dialog. How to fix this?

在此先感谢

推荐答案

我来晚了一点，但更好的后期从来就不是:-)
您可以使用下面的code：（我也看到这里）

I'm little late, but better late then never :-) you can use the code below: (I saw also here)

dialog = new Dialog(activity, android.R.style.Theme_Translucent_NoTitleBar);

dialog.setContentView(R.layout.activity_upload_photo_dialog);

Window window = dialog.getWindow();
window.setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);

//The below code is EXTRA - to dim the parent view by 70%
LayoutParams lp = window.getAttributes();
lp.dimAmount = 0.7f;
lp.flags = LayoutParams.FLAG_DIM_BEHIND;
dialog.getWindow().setAttributes(lp);
//Show the dialog
dialog.show();
