Normal dialog box

 button1=findViewById(R.id.dialog1);
        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
                        .setIcon(R.drawable.tuimg)//设置标题的图片
                        .setTitle("我是对话框")//设置对话框的标题
                        .setMessage("我是对话框的内容")//设置对话框的内容
                        //设置对话框的按钮
                        .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                Toast.makeText(DialogActivity.this, "点击了取消按钮", Toast.LENGTH_SHORT).show();
                                dialog.dismiss();
                            }
                        })
                        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                Toast.makeText(DialogActivity.this, "点击了确定的按钮", Toast.LENGTH_SHORT).show();
                                dialog.dismiss();
                            }
                        }).create();
                dialog.show();

        });

Semi-custom dialog

A view is also defined here

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<EditText
    android:id="@+id/dialog_edit"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    />
</LinearLayout>

 Called via the following statement:

View view = getLayoutInflater().inflate(R.layout.half_dialog_view, null);
final EditText editText = (EditText) view.findViewById(R.id.dialog_edit);

 button5=findViewById(R.id.dialog5);
        button5.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //调用其他的xml文件
                View view = getLayoutInflater().inflate(R.layout.half_dialog_view, null);
                final EditText editText = (EditText) view.findViewById(R.id.dialog_edit);
                AlertDialog dialog = new AlertDialog.Builder(DialogActivity.this)
                        .setIcon(R.drawable.tuimg)//设置标题的图片
                        .setTitle("半自定义对话框")//设置对话框的标题
                        .setView(view)
                        .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.dismiss();
                            }
                        })
                        .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                String content = editText.getText().toString();
                                Toast.makeText(DialogActivity.this, content, Toast.LENGTH_SHORT).show();
                                dialog.dismiss();
                            }
                        }).create();
                dialog.show();

            }
        });
