我尝试上面的代码显示3个选项的对话框。它工作正常，但我需要更改对话框的大小。可以帮助我。

Answer 1

试试这行代码：

builder3.create().getWindow().setLayout(300, 200);

希望它能帮助!!

Answer 2

只需添加以下代码

即可

Window window = Your_Dialog.getWindow();
window.setLayout(1300,900);

Answer 3

如果您想要屏幕尺寸

，请使用以下代码行

int width = getWindowManager().getDefaultDisplay().getWidth() - x;    
int height = getWindowManager().getDefaultDisplay().getHeight() - y; 
//where x and y are margin as required for ur dialog


AlertDialog.Builder builder3=new AlertDialog.Builder(MainActivity.this);
builder3.create().getWindow().setLayout(width, height);
builder3.setTitle("Pick your choice").setItems(options, new DialogInterface.OnClickListener() {
//rest of ur code
}

Answer 4

我认为你可以尝试创建一个对话框布局并在你的代码资源中调用它。

Answer 5

试

AlertDialog.Builder builder3=new AlertDialog.Builder(MainActivity.this);
Dialog d = builder3.setView(new View(this)).create();
d.getWindow().setLayout(600, 400);
d.show();

Answer 6

你还有标题栏吗？这可能会将您的对话框强制为特定大小。

在DialogFragment子类（或Dialog子类，不带getDialog()）中尝试此代码：

    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

无法更改android对话框大小
