0x002 简单使用

继承树：
Dialog是AlertDialog、DatePickerDialog、ProgressDialog等一些常用Dialog的直接或者间接父类，但是官网文档说我们应当避免直接使用父类，而应该使用他们的子类。

AlertDialog最简单使用方式：

代码：

AlertDialog.Builder builder=new AlertDialog.Builder(DialogActivity.this);
        builder.setTitle("SimpleAlert");
        builder.setMessage("are you ok");
        builder.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getApplicationContext(),"you click cancle",Toast.LENGTH_LONG).show();

            }
        });
        builder.setPositiveButton("Sure", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getApplicationContext(),"you click sure",Toast.LENGTH_LONG).show();

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

-说明：Dialog使用的是建造者模式，所以我们要用build来建造一个dialog，同时根据建造者模式的特性，我们还可以这么写：

    AlertDialog.Builder builder=new AlertDialog.Builder(DialogActivity.this);
          builder.setTitle("SimpleAlert").
          setMessage("are you ok").
          setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
              @Override
              public void onClick(DialogInterface dialog, int which) {
                  Toast.makeText(getApplicationContext(),"you click cancle",Toast.LENGTH_LONG).show();

              }
          }).
          setPositiveButton("Sure", new DialogInterface.OnClickListener() {
              @Override
              public void onClick(DialogInterface dialog, int which) {
                  Toast.makeText(getApplicationContext(),"you click sure",Toast.LENGTH_LONG).show();

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

DialogFragment
官网中推荐我们不应当这么使用，而是应该使用DialogFragment，因为这样可以更好地管理Dialog的生命周期和方法。所以接下来都会使用DialogFragment的方式来写
- 代码：
  //MyDialogFragment.java
  public class MyDialogFragment extends android.support.v4.app.DialogFragment {
  @NonNull
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
  AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
  builder.setTitle("first alert");
  builder.setMessage("are you OK");
  builder.setPositiveButton("Sure", new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {
  Toast.makeText(getContext(),"you click sure",Toast.LENGTH_LONG).show();
  }
  });
  builder.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {
  Toast.makeText(getContext(),"you click cancle",Toast.LENGTH_LONG).show();
```
    }
});
return builder.create();
}
}
//DialogActivity
MyDialogFragment myDialogFragment=new MyDialogFragment();
myDialogFragment.show(getSupportFragmentManager(),"");
```

0x003 AlertDialog

再添加一个按钮

代码：
public class NatureButtonFragment extends DialogFragment {
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder=new AlertDialog.Builder(getActivity());
builder.setTitle("more button")
.setMessage("more button")
//确认按钮
.setNegativeButton("SURE", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getContext(),"you click sure",Toast.LENGTH_LONG).show();

            }
        })
        //取消按钮
        .setPositiveButton("CANCLE", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getContext(),"you click cancle",Toast.LENGTH_LONG).show();

            }
        })
        //第三个按钮，不是确认也不是取消，而是介于二者中间，例如Remind Me Later
        .setNeutralButton("REMAIND ME LATER", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(getContext(),"you click later",Toast.LENGTH_LONG).show();
            }
        });
return builder.create();

}
}

添加一个列表
代码：
//ListDialogFragment.java
public class ListDialogFragment extends DialogFragment {
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final String s[] = new String[]{"item1", "item2", "item3"};
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("List")
.setItems(s, new DialogInterface.OnClickListener() {
@TargetApi(Build.VERSION_CODES.M)
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getContext(), "you click " + s[which], Toast.LENGTH_LONG).show();
}
});
return builder.create();
}
}

添加一列单选按钮
- 代码：
  public class ListDialogFragment extends DialogFragment {
  @NonNull
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
  final String s[] = new String[]{"item1", "item2", "item3"};
  AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
  builder.setTitle("List")
  .setItems(s, new DialogInterface.OnClickListener() {
  @TargetApi(Build.VERSION_CODES.M)
  @Override
  public void onClick(DialogInterface dialog, int which) {
  Toast.makeText(getContext(), "you click " + s[which], Toast.LENGTH_LONG).show();
  }
  });
  return builder.create();
  }
  }

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final String s[]={"item1","item2","item3"};
final boolean s2[]={true,false,false};

          AlertDialog.Builder builder=new AlertDialog.Builder(getContext());
          builder.setMultiChoiceItems(s, s2, new DialogInterface.OnMultiChoiceClickListener() {
              @Override
              public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                  Toast.makeText(getContext(),s[which]+" isChecked is "+isChecked,Toast.LENGTH_LONG).show();
              }
          });
          return builder.create();
      }
  }

在activity中处理按钮事件：

代码：
//EventBackDialogFragment .java
public class EventBackDialogFragment extends DialogFragment {
public interface EventBackDialogListener{
public void OnPositiveClick(DialogFragment dialogFragment);
public void OnNegativeClick(DialogFragment dialogFragment);
}
EventBackDialogListener mListener;
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

          AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
          builder.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
              @Override
              public void onClick(DialogInterface dialog, int which) {
                  mListener.OnNegativeClick(EventBackDialogFragment.this);
              }
          })
                  .setPositiveButton("SURE", new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {
                          mListener.OnPositiveClick(EventBackDialogFragment.this);
                      }
                  });
          return builder.create();
  
      }
  
      @Override
      public void onAttach(Activity activity) {
  
          super.onAttach(activity);
          mListener= (EventBackDialogListener) activity;
      }
  }
  //DialogActivity
public class DialogActivity extends ListActivity implements   EventBackDialogFragment.EventBackDialogListener {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
    EventBackDialogFragment eventBackDialogFragment=new EventBackDialogFragment();
      eventBackDialogFragment.show(getFragmentManager(),"");
  }
 @Override
public void OnPositiveClick(android.app.DialogFragment dialogFragment) {
Toast.makeText(getApplicationContext(),"you  click Sure",Toast.LENGTH_LONG).show();

}

@Override
public void OnNegativeClick(android.app.DialogFragment dialogFragment) {
 Toast.makeText(getApplicationContext(),"you  click Cancle",Toast.LENGTH_LONG).show();

}
}

0x004 ProgressDialog

概述：progressDialog和DatapickerDilaog等其实不过是AlertDialog的子类，所以说白了，不过是一个封装好的Dialog，比如progressDlialog不过是封装了一个progress的AlertDialog。

progressDialog进度条
- 代码：
  public class ProgressDialogFragment extends DialogFragment {
  @TargetApi(Build.VERSION_CODES.M)
  @NonNull
  @Override
  public Dialog onCreateDialog(Bundle savedInstanceState) {
```
        ProgressDialog progressDialog=new ProgressDialog(getContext());
        return progressDialog;
    }
}
```

带进度的progress
在ProgressDialog.java中，有一个方法名为setProgressStyle(int style ),我们跳到mProgressStyle,就会看到
public static final int STYLE_SPINNER = 0;//spinner进度条
public static final int STYLE_HORIZONTAL = 1;//horizontal进度条

代码：

 public class ProgressHorizatalDialogFragment extends DialogFragment {
   @TargetApi(Build.VERSION_CODES.M)
   @NonNull
   @Override
   public Dialog onCreateDialog(Bundle savedInstanceState) {

       ProgressDialog progressDialog=new ProgressDialog(getContext());
       progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
       progressDialog.setMessage("正在下载");
       progressDialog.setProgress(20);
       progressDialog.setMax(100);
       return progressDialog;
   }
 }
