如果在AlertDialog中创建EditText单元后调用一个方法，用于一般用途，不是更流畅吗?

public static void EditTextListPicker(final Activity activity, final EditText EditTextItem, final String SelectTitle, final String[] SelectList) {
    EditTextItem.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(activity);
            builder.setTitle(SelectTitle);
            builder.setItems(SelectList, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialogInterface, int item) {
                    EditTextItem.setText(SelectList[item]);
                }
            });
            builder.create().show();
            return false;
        }
    });
}

这太简单了

final CharSequence[] items = {"Take Photo", "Choose from Library", "Cancel"};

AlertDialog.Builder builder = new AlertDialog.Builder(MyProfile.this);

builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int item) {
        if (items[item].equals("Take Photo")) {
            getCapturesProfilePicFromCamera();
        } else if (items[item].equals("Choose from Library")) {
            getProfilePicFromGallery();
        } else if (items[item].equals("Cancel")) {
            dialog.dismiss();
        }
    }
});
builder.show();

}

下面的代码用于在AlertDialog中显示自定义列表

AlertDialog.Builder builderSingle = new AlertDialog.Builder(DialogActivity.this);
builderSingle.setIcon(R.drawable.ic_launcher);
builderSingle.setTitle("Select One Name:-");

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(DialogActivity.this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.add("Hardik");
arrayAdapter.add("Archit");
arrayAdapter.add("Jignesh");
arrayAdapter.add("Umang");
arrayAdapter.add("Gatti");

builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String strName = arrayAdapter.getItem(which);
                AlertDialog.Builder builderInner = new AlertDialog.Builder(DialogActivity.this);
                builderInner.setMessage(strName);
                builderInner.setTitle("Your Selected Item is");
                builderInner.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,int which) {
                                dialog.dismiss();
                            }
                        });
                builderInner.show();
            }
        });
builderSingle.show();

private void AlertDialogue(final List<Animals> animals) {
 final AlertDialog.Builder alertDialog = new AlertDialog.Builder(AdminActivity.this);
 alertDialog.setTitle("Filter by tag");

 final String[] animalsArray = new String[animals.size()];

 for (int i = 0; i < tags.size(); i++) {
  animalsArray[i] = tags.get(i).getanimal();

 }

 final int checkedItem = 0;
 alertDialog.setSingleChoiceItems(animalsArray, checkedItem, new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {

   Log.e(TAG, "onClick: " + animalsArray[which]);

  }
 });


 AlertDialog alert = alertDialog.create();
 alert.setCanceledOnTouchOutside(false);
 alert.show();

}

使用“import android.app.AlertDialog;”导入，然后写入

    String[] items = {"...","...."};             
    AlertDialog.Builder build = new AlertDialog.Builder(context);
    build.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //do stuff....
        }
    }).create().show();
