android：自定义对话框

上文的dialog.xml中，确定和取消按钮都是TextView，所以需要自定义按钮的背景

/confirm/i_button_style.xml  (所有的color需要自定义)

cancel_button_style.xml 

final alertDialog dialog = new alertDialog.Builder(xxxClass.this).create();
dialog.setCancelable(false); //点击对话框以外的位置，不消失
dialog.show();

Window window = dialog.getWindow();
window.setContentView(R.layout.dialog);
//标题
TextView title = window.findViewById(R.id.dialog_title);
title.setText("dialog_title");

//内容
TextView message = window.findViewById(R.id.dialog_message);
message.setText("dialog_message ");

//确定按钮
LinearLayout confirm = window.findViewById(R.id.dialog_/confirm/i);
/confirm/i.setonClickListener(new View.onClickListener() {
    @Override
    public void onClick(View v) {
        //xxx
    }
});

//取消按钮
LinearLayout cancel = window.findViewById(R.id.dialog_cancel);
cancel.setonClickListener(new View.onClickListener() {
    @Override
    public void onClick(View v) {
        //xxx
    }
});
