Android开发中最常用的就是Dialog类，除了自定义dialog布局，最多的就是用在弹出对话框、进度条、输入框、单选、复选框。

1、选择对话框：

AlertDialog.Builder dialog = new AlertDialog.Builder(this); 
dialog.setTitle("选择对话框"); 
dialog.setMessage("请选择确认或取消"); 
dialog.setCancelable(false); //设置按下返回键不能消失 
dialog.setPositiveButton("确认", new DialogInterface.OnClickListener() { 
  @Override 
  public void onClick(DialogInterface dialog, int which) { 
    Toast.makeText(MainActivity.this, "您选择了确认", Toast.LENGTH_LONG).show(); 
      } 
    }); 
    dialog.setNegativeButton("取消", new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int which) { 
        Toast.makeText(MainActivity.this, "您选择了取消", Toast.LENGTH_LONG).show(); 
      } 
    }); 
dialog.show();//显示弹出窗口

2、进度条

ProgressDialog progressDialog = new ProgressDialog(this); 
progressDialog.setTitle("显示进度条"); 
progressDialog.setMessage("加载中..."); 
progressDialog.setCancelable(true); 
progressDialog.show();

3、弹出输入框

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setTitle("弹出输入框"); 
builder.setMessage("输入内容"); 
final EditText editText = new EditText(this); 
builder.setView(editText); 
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 
      @Override 
  public void onClick(DialogInterface dialog, int which) { 
    Toast.makeText(MainActivity.this, "您输入了" + editText.getText().toString(), Toast.LENGTH_SHORT).show(); 
      } 
  }); 
builder.setNegativeButton("取消", null); 
builder.show();

4、弹出单选框

final AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setTitle("弹出单选框"); 
final String[] choice = new String[]{"Java", "C++", "PHP"}; 
builder.setSingleChoiceItems(choice, 0, 
  new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
      Toast.makeText(MainActivity.this, "您选择了" + choice[which], Toast.LENGTH_LONG).show(); 
      dialog.dismiss(); // 让窗口消失 
    } 
  }); 
builder.create().show();

5、弹出复选框

final AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setTitle("弹出多选框"); 
final String[] choice = new String[]{"Android", "IOS", "Windos Phone"}; // 选择项 
final boolean[] isCheck = new boolean[choice.length]; // 是否被选中 
builder.setMultiChoiceItems(choice, null, 
  new DialogInterface.OnMultiChoiceClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
      if (isChecked == true) 
        isCheck[which] = true; 
      else if(isChecked == false) 
        isCheck[which] = false; 
     } 
  }); 
builder.setNegativeButton("取消", null); 
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 
  @Override 
  public void onClick(DialogInterface dialog, int which) { 
    String isSelected = "您选择了"; 
    for (int i = 0; i < choice.length; i++) { 
      if (isCheck[i] == true) { 
        isSelected += choice[i]+","; // 将选择的内容加上 
      } 
    } 
    Toast.makeText(MainActivity.this, isSelected, Toast.LENGTH_LONG).show(); 
   } 
}); 
builder.create(); 
builder.show();

6、自定义布局的Dialog

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
 final AlertDialog dialog = builder.create(); 
 View view = View.inflate(this, R.layout.personal_modifyhead_dialog, null); 
 dialog.setView(view, 0, 0, 0, 0);// 设置边距为0,保证在2.x的版本上运行没问题 
 dialog.show(); 
 
 AutoRelativeLayout rl_photograph = (AutoRelativeLayout) view.findViewById(R.id.rl_photograph); 
 rl_photograph.setOnClickListener(new View.OnClickListener() { 
   @Override 
   public void onClick(View v) { 
     presenter.modiftHeadFromPhotograph(); 
     dialog.dismiss(); 
   } 
 }); 
 
 AutoRelativeLayout rl_album = (AutoRelativeLayout) view.findViewById(R.id.rl_album); 
 rl_album.setOnClickListener(new View.OnClickListener() { 
   @Override 
   public void onClick(View v) { 
     presenter.modifyHeadFromAlbum(); 
     dialog.dismiss(); 
   } 
 });
