今天就跟大家聊聊有關如何在Android中利用Dialog實現一個對話框功能，可能很多人都不太了解，為了讓大家更加了解，小編給大家總結了以下內容，希望大家根據這篇文章可以有所收獲。

一、普通對話框

AlertDialog.Builder builder = new AlertDialog.Builder(activity);
builder.setTitle("溫馨提示");//標題
builder.setMessage("天氣冷，注意保暖");
builder.setIcon(R.mipmap.ic_launcher);
builder.create();
builder.show();

二、確定取消對話框

builder.setTitle("確定取消對話框");
builder.setMessage("請選擇確定或取消");
builder.setIcon(R.mipmap.ic_launcher);
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
 //正能量按鈕 Positive
 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你點擊了確定", Toast.LENGTH_SHORT).show();
 }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你選擇了取消", Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();

三、多按鈕對話框

builder.setTitle("多個按鈕對話框");
builder.setMessage("請選擇");
builder.setIcon(R.mipmap.ic_launcher);
builder.setPositiveButton("我沒玩夠", new DialogInterface.OnClickListener() {

 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "繼續瀏覽精彩內容", Toast.LENGTH_SHORT).show();
 }
});
builder.setNeutralButton("開啟", new DialogInterface.OnClickListener() {

 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "起床了", Toast.LENGTH_SHORT).show();
 }
});
builder.setNegativeButton("我累了，要休息一下", new DialogInterface.OnClickListener() {

 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "歡迎再來", Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();

四、列表對話框

final String arrItem[] = getResources().getStringArray(R.array.aikaifa);
builder.setItems(arrItem, new DialogInterface.OnClickListener() {

 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你選擇了第" + arrItem[which], Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();

五、帶Adapter的對話框

builder.setTitle("帶Adapter的對話框");
builder.setIcon(R.mipmap.ic_launcher);
final List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
int arrImg[] = {R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher,
 R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher,
 R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher, R.mipmap.ic_launcher};
for (int i = 0; i < arrImg.length; i++) {
 Map<String, Object> map = new HashMap<String, Object>();
 map.put("img", arrImg[i]);
 map.put("title", "愛開發" + i);
 list.add(map);
}
SimpleAdapter adapter = new SimpleAdapter(activity, list, R.layout.list_item, new String[]{"img", "title"}, new int[]{R.id.iv, R.id.tv});
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
 @Override
 public void onClick(DialogInterface dialog, int which) {
 Toast.makeText(activity, "你選擇了" + list.get(which).get("title").toString().trim(), Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();

六、單選對話框

builder.setTitle("單選對話框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setSingleChoiceItems(R.array.aikaifa, 0, new DialogInterface.OnClickListener() {

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

 }
});
builder.create().show();

單選對話框

七、多選對話框

builder.setTitle("多選對話框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setMultiChoiceItems(R.array.aikaifa, null, new DialogInterface.OnMultiChoiceClickListener() {

 @Override
 public void onClick(DialogInterface dialog, int which, boolean isChecked) {
 Toast.makeText(activity, which+""+isChecked, Toast.LENGTH_SHORT).show();
 }
});
builder.create().show();

多選對話框

八、日期對話框

 DatePickerDialog datePickerDialog=new DatePickerDialog(activity,
 new DatePickerDialog.OnDateSetListener() {

  @Override
  public void onDateSet(DatePicker view, int year, int monthOfYear,
 int dayOfMonth) {
Toast.makeText(activity,
 year+"年"+(monthOfYear+1)+"月"+dayOfMonth+"日", Toast.LENGTH_SHORT).show();
  }
 },
 2017, 02, 9);
datePickerDialog.show();

日期對話框

九、時間對話框

TimePickerDialog timePickerDialog=new TimePickerDialog(activity,
 new TimePickerDialog.OnTimeSetListener() {

  @Override
  public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Toast.makeText(activity,
 hourOfDay+"小時"+minute+"分鐘", Toast.LENGTH_SHORT).show();
  }
 },
 17, 49, true);
timePickerDialog.show();

時間對話框

十、自定義對話框

View view= LayoutInflater.from(activity).inflate(R.layout.dialog_login, null);
builder.setView(view);
builder.create();
final EditText et_phone=(EditText)view.findViewById(R.id.et_phone);
final EditText et_password=(EditText)view.findViewById(R.id.et_password);
Button btn_submit=(Button)view.findViewById(R.id.btn_submit);
btn_submit.setOnClickListener( new View.OnClickListener() {
 @Override
 public void onClick(View view) {
 Toast.makeText(activity, "手機號碼:"+et_phone.getText().toString()+" 短信驗證碼:"+et_password.getText().toString(), Toast.LENGTH_SHORT).show();
 }
});
builder.show();

自定義對話框

 <LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"

  android:layout_height="48dp"
  android:layout_marginLeft="10dp"
  android:layout_weight="2"
  android:enabled="false"
  android:gravity="center"
  android:text="點擊獲取"
  android:textColor="#000000" />
 </LinearLayout>

 <Button
