前言
对确认取消对话框的封装。
前提：调用对话框的Activity必须继承FragmentActivity及其子类（比如AppCompatActivity）。
效果图
代码分析
ConfirmCancelDialog继承DialogFragment；
默认展现左侧、中间、右侧三个按钮，通过DialogSetListener控制按钮的隐藏【比如，如果想要展现一个按钮，那么需要手动将其他两个按钮隐藏】；
通过DialogClickListener实现左侧、中间、右侧三个按钮的监听事件。
实现了点击空白区域隐藏对话框的功能。
使用步骤
一、项目组织结构图
注意事项：
1、导入类文件后需要change包名以及重新import R文件路径
2、Values目录下的文件（strings.xml、dimens.xml、colors.xml等），如果项目中存在，则复制里面的内容，不要整个覆盖
二、导入步骤
将ConfirmCancelDialog.java文件复制到项目中

三、使用方法
只展现一个确定按钮
btn_confirm.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ConfirmCancelDialog dialog = ConfirmCancelDialog.getInstance(MainActivity.this,true,new ConfirmCancelDialog.DialogSetListener() { public void setDialog(TextView title, TextView message, Button leftBtn, Button betweenBtn, Button rightBtn) { message.setText("请检查用户名"); leftBtn.setVisibility(GONE); betweenBtn.setVisibility(GONE); } }); dialog.setDialogClickListener(new ConfirmCancelDialog.DialogClickListener() { @Override public void betweenClickListener() { // TODO Auto-generated method stub } @Override public void cancelClickListener() { // TODO Auto-generated method stub } @Override public void confirmClickListener() { Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show(); } @Override public void onDismissListener() { } }); dialog.show(getSupportFragmentManager(), "confirmDialog"); } });
展现确定和取消两个按钮
btn_confirmcancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ConfirmCancelDialog dialog = ConfirmCancelDialog.getInstance(MainActivity.this,new ConfirmCancelDialog.DialogSetListener() { public void setDialog(TextView title, TextView message, Button leftBtn, Button betweenBtn, Button rightBtn) { message.setText("是否退出？"); betweenBtn.setVisibility(GONE); } }); dialog.setDialogClickListener(new ConfirmCancelDialog.DialogClickListener() { @Override public void betweenClickListener() { // TODO Auto-generated method stub } @Override public void cancelClickListener() { Toast.makeText(MainActivity.this,"取消",Toast.LENGTH_SHORT).show(); } @Override public void confirmClickListener() { Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show(); } @Override public void onDismissListener() { } }); dialog.show(getSupportFragmentManager(), "confirmCancelDialog"); } });
展现三个按钮，并且修改了按钮的文本
btn_confirmcancelbetween.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ConfirmCancelDialog dialog = ConfirmCancelDialog.getInstance(MainActivity.this,new ConfirmCancelDialog.DialogSetListener() { public void setDialog(TextView title, TextView message, Button leftBtn, Button betweenBtn, Button rightBtn) { message.setText("是否保存？"); betweenBtn.setText("不保存"); rightBtn.setText("保存"); } }); dialog.setDialogClickListener(new ConfirmCancelDialog.DialogClickListener() { @Override public void betweenClickListener() { Toast.makeText(MainActivity.this,"不保存",Toast.LENGTH_SHORT).show(); } @Override public void cancelClickListener() { Toast.makeText(MainActivity.this,"取消",Toast.LENGTH_SHORT).show(); } @Override public void confirmClickListener() { Toast.makeText(MainActivity.this,"保存",Toast.LENGTH_SHORT).show(); } @Override public void onDismissListener() { } }); dialog.show(getSupportFragmentManager(), "confirmCancelBetweenDialog"); } });
展现没有标题的对话框
btn_notitle.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ConfirmCancelDialog dialog = ConfirmCancelDialog.getInstance(MainActivity.this,new ConfirmCancelDialog.DialogSetListener() { public void setDialog(TextView title, TextView message, Button leftBtn, Button betweenBtn, Button rightBtn) { message.setText("发现新版本，是否升级？"); title.setVisibility(GONE); betweenBtn.setVisibility(GONE); } }); dialog.setDialogClickListener(new ConfirmCancelDialog.DialogClickListener() { @Override public void betweenClickListener() { // TODO Auto-generated method stub } @Override public void cancelClickListener() { Toast.makeText(MainActivity.this,"取消",Toast.LENGTH_SHORT).show(); } @Override public void confirmClickListener() { Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show(); } @Override public void onDismissListener() { } }); dialog.show(getSupportFragmentManager(), "noTitleDialog"); } });
展现内容文本很多的对话框（需要手动设置居左对齐）
btn_message.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ConfirmCancelDialog dialog = ConfirmCancelDialog.getInstance(MainActivity.this,new ConfirmCancelDialog.DialogSetListener() { public void setDialog(TextView title, TextView message, Button leftBtn, Button betweenBtn, Button rightBtn) { message.setText("当内容文本很多的时候，可以手动设置居左【message.setGravity(Gravity.LEFT)】"); message.setGravity(Gravity.LEFT);//如果内容很多的话，需要手动设置居左 betweenBtn.setVisibility(GONE); } }); dialog.setDialogClickListener(new ConfirmCancelDialog.DialogClickListener() { @Override public void betweenClickListener() { // TODO Auto-generated method stub } @Override public void cancelClickListener() { Toast.makeText(MainActivity.this,"取消",Toast.LENGTH_SHORT).show(); } @Override public void confirmClickListener() { Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show(); } @Override public void onDismissListener() { } }); dialog.show(getSupportFragmentManager(), "noMessageDialog"); } });
