1.普通对话框

代码如下：

private void SimpleDialog() {
    btn1 = (Button) findViewById(R.id.btn_1);
    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //创建构造者
            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            //添加对话框内容
            builder.setIcon(R.mipmap.ic_launcher);
            builder.setTitle("对话框");
            builder.setMessage("确认删除吗？");
            builder.setPositiveButton("确认", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(MainActivity.this, "确认删除", Toast.LENGTH_SHORT).show();
                }
            });
            builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(MainActivity.this, "取消删除", Toast.LENGTH_SHORT).show();
                }
            });
            //创建对话框
            AlertDialog alertDialog = builder.create();
            //显示对话框
            alertDialog.show();
        }
    });
}

代码如下：

private void SelectDialog() {
    btn2 = (Button) findViewById(R.id.btn_2);
    btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
            builder.setIcon(R.mipmap.ic_launcher_round);
            builder.setTitle("单选框");

            builder.setPositiveButton("确认", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(MainActivity.this, "确认", Toast.LENGTH_SHORT).show();
                }
            });

            final String[] str = {"java", "php", "python"};

            builder.setSingleChoiceItems(str, 2, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(MainActivity.this, "" + str[which], Toast.LENGTH_SHORT).show();
                }
            });

            //创建对话框
            AlertDialog alertDialog = builder.create();
            //显示对话框

                public void onClick(DialogInterface dialog, int which) {
                    for (int i = 0; i < booleans.length; i++) {
                        if (booleans[i]) {
                            int count = i + 1;
