安卓中在代码中设置dialog的样式

直接在代码中设置dialog的样式，代码如下：

public void onClick(View v) {            final EditText inputServer = new EditText(ActivityAccoutManage.this);            inputServer.setSelectAllOnFocus(true);            AlertDialog.Builder builder = new AlertDialog.Builder(Activity.this);            builder.setTitle("设置标题")                    .setView(inputServer)                    .setNegativeButton("取消", null)                    .setPositiveButton("确定", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) {    Toast.makeText(Activity.this, "确定", Toast.LENGTH_LONG).show();    }  });   builder.show();  }
