我正在处理应用程序,我想将对话框显示为屏幕大小.所以我使用下面的代码.我通过这里得到了解决方案
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);
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);
但我希望对话框出现在中心对齐的位置.现在它显示在窗口的顶部.
我尝试使用lp.garvity = Gravity.center,但没有用.
如果设备方向改变,我需要再按ok按钮关闭对话框.如何解决这个问题？

解决方法
我迟到了,但是迟到的时候再好不过了:-)
你可以使用下面的代码:(我也看到了 here)
你可以使用下面的代码:(我也看到了 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();
希望我帮忙……
