无法设置警报框的宽度

Question

我有这个简单的警告框，显示一条简单的消息，但是当文本太长时，它会被切断..有没有办法可以设置警报框的宽度.. < / p>

我试过Ext.Msg.MinWidth = 300;

但那不起作用

onForgotPwdTap: function(button, e, eOpts) {        
        Ext.Msg.alert('Forgot Password?', 'Please contact your administrator for password assistance.', Ext.emptyFn);
    }

你可以尝试获取这样的屏幕尺寸：

Display display = getWindowManager().getDefaultDisplay(); 
int mwidth = display.getWidth();
int mheight = display.getHeight();
And then alter the Dialog like this:

AlertDialog.Builder adb = new AlertDialog.Builder(this);
Dialog d = adb.setView(new View(this)).create();
// (That new View is just there to have something inside the dialog that can grow big enough to cover the whole screen.)

d.show();

WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(d.getWindow().getAttributes());
lp.width = mwidth;
lp.height = myheight;

//change position of window on screen
lp.x = mwidth/2; //set these values to what work for you; probably like I have here at
lp.y = mheight/2;        //half the screen width and height so it is in center

//set the dim level of the background
lp.dimAmount=0.1f; //change this value for more or less dimming

d.getWindow().setAttributes(lp);

//add a blur/dim flags
d.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND | WindowManager.LayoutParams.FLAG_DIM_BEHIND);
