Answer 1

试试这个：

TextView tv = new TextView(this);
tv.setBackgroundColor(0xffeeeeee);
tv.setTextColor(0xff000000);
tv.setTextSize(22);
SpannableStringBuilder b = new SpannableStringBuilder();
b.append("some text here, it will be placed in several lines and then you will see the numbers:\n");
Object lms = new LeadingMarginSpan.Standard(12, 28);
int start = b.length();
b.append("1. first of all it should work and this text should be nicely indented\n");
b.append("2. if not, some bugs exist\n");
b.setSpan(lms, start, b.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
lms = new LeadingMarginSpan.Standard(-12);
start = b.length();
b.append("and this is the rest of the text");
b.setSpan(lms, start, b.length(), Spanned.SPAN_EXCLUSIVE_INCLUSIVE);
tv.setText(b);
setContentView(tv);

您可以创建Custom Dialog来完成此任务。使用Relative or Linear Layout制作图片中的布局，然后将该布局设置为Dialog。

以下是实现此目的的示例 Android Custom Dialog Example

在按钮内点击：

自定义对话框：

final Dialog dialog = new Dialog(context);
            dialog.setContentView(R.layout.custom);
            dialog.setTitle("Title...");


            TextView text = (TextView) dialog.findViewById(R.id.text1);
                    TextView text = (TextView) dialog.findViewById(R.id.text2);
                    TextView text = (TextView) dialog.findViewById(R.id.text3);
            text1.setText("Your Header");
                    text2.setText("1. body");
                    text3.setText("2. body");

 Button dialogButton = (Button) dialog.findViewById(R.id.dialogButton);

            dialogButton.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    dialog.dismiss();
                }
            });
        dialog.show();
