一、常用對話框

1.普通對話框

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("標題");
        builder.setMessage("內容");
        builder.setIcon(R.mipmap.ic_launcher);//圖片
        builder.setCancelable(false);//點擊別處是否取消顯示
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, "確定", 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", Toast.LENGTH_SHORT).show();
            }
        });
        //builder.show();
        AlertDialog alertDialog = builder.create();
        alertDialog.show();

2.單選對話框

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("標題");
        final String[] s=new String[]{"籃球","羽毛球","足球"};
        builder.setSingleChoiceItems(s, 1, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, s[which], Toast.LENGTH_SHORT).show();
            }
        });
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setCancelable(false);
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, "確定", 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", Toast.LENGTH_SHORT).show();
            }
        });
        //builder.show();
        AlertDialog alertDialog = builder.create();
        alertDialog.show();

3.多選對話框

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("標題");
        final String[] s=new String[]{"籃球","羽毛球","足球"};
        final boolean[] b=new boolean[]{false,false,false};
        builder.setMultiChoiceItems(s, b, new DialogInterface.OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                Toast.makeText(MainActivity.this, s[which], Toast.LENGTH_SHORT).show();
            }
        });
        builder.setIcon(R.mipmap.ic_launcher);
        builder.setCancelable(false);
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, "確定", Toast.LENGTH_SHORT).show();
                for (int i = 0; i < b.length ; i++) {
                    if (b[i]){
                        Toast.makeText(MainActivity.this, s[i], 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", Toast.LENGTH_SHORT).show();
            }
        });
        //builder.show();
        AlertDialog alertDialog = builder.create();
        alertDialog.show();

4.自定義對話框（******）

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("標題");
        final View inflate = LayoutInflater.from(this).inflate(R.layout.alert_layout, null);
        builder.setView(inflate);
        ImageView viewById = inflate.findViewById(R.id.image1);

        builder.setIcon(R.mipmap.ic_launcher);
        builder.setCancelable(false);
        builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.this, "確定", 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", Toast.LENGTH_SHORT).show();
            }
        });
        //builder.show();
        final AlertDialog alertDialog = builder.create();
        viewById.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                alertDialog.dismiss();
            }
        });
        alertDialog.show();

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent">
    <TextView
        android:id="@+id/text1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textSize="30sp"
        android:text="一張圖片"></TextView>
    <ImageView
        android:id="@+id/image1"
        android:layout_width="wrap_content"
        android:src="@mipmap/youhua"
        android:layout_height="wrap_content"></ImageView>

</LinearLayout>

5.水平進度條對話框

final ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("標題");
        progressDialog.setMax(100);
        progressDialog.setProgress(10);
        progressDialog.setSecondaryProgress(20);
        progressDialog.setProgressStyle(progressDialog.STYLE_HORIZONTAL);
        progressDialog.show();

        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            int index=0;
            @Override
            public void run() {
                index+=10;
                progressDialog.setProgress(index);
                if (index>=100){
                    progressDialog.cancel();
                    progressDialog.dismiss();
                }
            }
        },0,1000);
        progressDialog.show();

6.圓形進度條對話框

7.日期選擇對話框

Calendar calendar = Calendar.getInstance();
        calendar.get(Calendar.YEAR);
        DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                Toast.makeText(MainActivity.this, year+"年"+(month+1)+"月"+dayOfMonth, Toast.LENGTH_SHORT).show();
            }
        },calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DAY_OF_MONTH));
        datePickerDialog.show();

8.時間選擇對話框

Calendar calendar = Calendar.getInstance();
        TimePickerDialog timePickerDialog = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                Toast.makeText(MainActivity.this, hourOfDay+":"+minute, Toast.LENGTH_SHORT).show();
            }
        },calendar.get(Calendar.HOUR),calendar.get(Calendar.MINUTE),true);
        timePickerDialog.show();

二、自定義對話框

1.按鈕

//創建類繼承Dialog
1.宣告介面

public interface YesOnclick{
        void click();
    }

2.宣告成員變數

    private YesOnclick yesOnclick;

3.設定->給介面賦值

    public void setYesOnclick(YesOnclick yesOnclick) {
        this.yesOnclick = yesOnclick;
    }

完整步驟

public interface YesOnclick{
        void click();
    }

    private YesOnclick yesOnclick;

    public void setYesOnclick(YesOnclick yesOnclick) {
        this.yesOnclick = yesOnclick;
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_layout);
        initView();
        mes1.setText(strMes);
        title1.setText(strti);
        queding1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
                yesOnclick.click();
            }
        });
        quxiao1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
                noOnclick.click();
            }
        });
    }

呼叫

MyDialog myDialog = new MyDialog(this);
        myDialog.setStrti("標題45564546564");
        myDialog.setStrMes("內容123456789");
        myDialog.setNoOnclick(new MyDialog.NoOnclick() {
            @Override
            public void click() {
                Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
            }
        });
        myDialog.setYesOnclick(new MyDialog.YesOnclick() {
            @Override
            public void click() {
                Toast.makeText(MainActivity.this, "確定", Toast.LENGTH_SHORT).show();
            }
        });
        myDialog.show();

1.文本

1.findById

 title1 = (TextView) findViewById(R.id.title1);

2.成員變數

private String strti;

3.設定set方法

    public void setStrti(String strti) {
        this.strti = strti;
    }

4.系結

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_layout);
        initView();
   	    title1.setText(strti);
    }

5.呼叫

MyDialog myDialog = new MyDialog(this);
        myDialog.setStrti("標題45564546564");
        myDialog.setStrMes("內容123456789");
        myDialog.setNoOnclick(new MyDialog.NoOnclick() {
            @Override
            public void click() {
                Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
            }
        });
        myDialog.setYesOnclick(new MyDialog.YesOnclick() {
            @Override
            public void click() {
                Toast.makeText(MainActivity.this, "確定", Toast.LENGTH_SHORT).show();
            }
        });
        myDialog.show();
