Android开发：常用Dialog的几种格式显示,普通，列表，单选，多选，可编辑dialog等

Android中几种常见的dialog显示格式，话不多说，直接先上图

首先是Java代码

import android.app.Dialog;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    private Button btn_Normal;      // 普通
    private Button btn_List;        // 列表
    private Button btn_Choice;      // 单选
    private Button btn_MoreChoice;  // 多选
    private Button btn_EditText;    //可输入

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn_Normal = findViewById(R.id.normal_btn);
        btn_List = findViewById(R.id.list_btn);
        btn_Choice = findViewById(R.id.choice_btn);
        btn_MoreChoice = findViewById(R.id.more_choice_btn);
        btn_EditText =  findViewById(R.id.editext_btn);

        ButtonOnClickListener bocl = new ButtonOnClickListener();
        btn_Normal.setOnClickListener(bocl);
        btn_List.setOnClickListener(bocl);
        btn_Choice.setOnClickListener(bocl);
        btn_MoreChoice.setOnClickListener(bocl);
        btn_EditText.setOnClickListener(bocl);
    }

    class ButtonOnClickListener implements View.OnClickListener{
        @Override
        public void onClick(View v) {
            switch (v.getId()) {
                case R.id.normal_btn:
                    dialogNormal();     // 普通
                    break;
                case R.id.list_btn:
                    dialogList();       // 列表
                    break;
                case R.id.choice_btn:
                    dialogChoice();     // 单选
                    break;
                case R.id.more_choice_btn:
                    dialogMoreChoice(); // 多选
                    break;
                case R.id.editext_btn:
                    dialogEditText();   //可编辑
                    break;
                default:
                    break;
            }
        }
    }

    /**
     * 普通
     */
    private void dialogNormal() {
        DialogInterface.OnClickListener dialogOnclicListener = new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                switch (which) {
                    case Dialog.BUTTON_POSITIVE:
                        Toast.makeText(MainActivity.this, "确认",
                                Toast.LENGTH_SHORT).show();
                        break;

下来是布局文件

OK，大概就是这样了，代码也比较的短，如果没弄懂的可以在底下留言
