android调整对话框长宽

GridLayout g1 = (GridLayout) getLayoutInflater().inflate(R.layout.change,null);
Dialog dialog =  new AlertDialog.Builder(MainActivity.this).setView(g1).create();
dialog.show();
dialog.getWindow().setLayout(600,600);//设置dialog的长宽都为600

第二种方式：

View view = inflater.inflate(R.layout.password_dialog, null);
final Dialog dialog = new AlertDialog.Builder(context).create();
dialog.show();
dialog.setContentView(view);
dialog.getWindow().setLayout(620, 414);
