- 普通的对话框
AlertDialog dialog = new AlertDialog.Builder(this) .setIcon(R.mipmap.icon)//设置标题的图片 .setTitle("我是对话框")//设置对话框的标题 .setMessage("我是对话框的内容")//设置对话框的内容 //设置对话框的按钮 .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "点击了取消按钮", Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, "点击了确定的按钮", Toast.LENGTH_SHORT).show(); dialog.dismiss(); } }).create(); dialog.show();- 列表对话框
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"}; AlertDialog dialog = new AlertDialog.Builder(this) .setIcon(R.mipmap.icon)//设置标题的图片 .setTitle("列表对话框")//设置对话框的标题 .setItems(items, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, items[which], Toast.LENGTH_SHORT).show(); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }).create(); dialog.show();- 单选列表对话框
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"}; AlertDialog dialog = new AlertDialog.Builder(this) .setIcon(R.mipmap.icon)//设置标题的图片 .setTitle("单选列表对话框")//设置对话框的标题 .setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(MainActivity.this, items[which], Toast.LENGTH_SHORT).show(); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }).create(); dialog.show();- 多选列表对话框
final String items[] = {"我是Item一", "我是Item二", "我是Item三", "我是Item四"}; final boolean checkedItems[] = {true, false, true, false}; AlertDialog dialog = new AlertDialog.Builder(this) .setIcon(R.mipmap.icon)//设置标题的图片 .setTitle("多选对话框")//设置对话框的标题 .setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { checkedItems[which] = isChecked; } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { for (int i = 0; i < checkedItems.length; i++) { if (checkedItems[i]) { Toast.makeText(MainActivity.this, "选中了" + i, Toast.LENGTH_SHORT).show(); } } dialog.dismiss(); } }).create(); dialog.show();- 完全自定义的对话框
1.首先我们需要自定义Dialog的style，让他自己本有的东西全部透明，然后在设置我们自己的内容就可以达到完全自定义的效果了。
<!--对话框的样式--> <style name="NormalDialogStyle"> <!--对话框背景 --> <item name="android:windowBackground">@android:color/transparent</item> <!--边框 --> <item name="android:windowFrame">@null</item> <!--没有标题 --> <item name="android:windowNoTitle">true</item> <!-- 是否浮现在Activity之上 --> <item name="android:windowIsFloating">true</item> <!--背景透明 --> <item name="android:windowIsTranslucent">false</item> <!-- 是否有覆盖 --> <item name="android:windowContentOverlay">@null</item> <!--进出的显示动画 --> <item name="android:windowAnimationStyle">@style/normalDialogAnim</item> <!--背景变暗--> <item name="android:backgroundDimEnabled">true</item> </style> <!--对话框动画--> <style name="normalDialogAnim" parent="android:Animation"> <item name="@android:windowEnterAnimation">@anim/normal_dialog_enter</item> <item name="@android:windowExitAnimation">@anim/normal_dialog_exit</item> </style>2.接下来就可以为对话框设置我们自定义的style了.
/** * 自定义对话框 */ private void customDialog() { final Dialog dialog = new Dialog(this, R.style.NormalDialogStyle); View view = View.inflate(this, R.layout.dialog_normal, null); TextView cancel = (TextView) view.findViewById(R.id.cancel); TextView confirm = (TextView) view.findViewById(R.id.confirm); dialog.setContentView(view); //使得点击对话框外部不消失对话框 dialog.setCanceledOnTouchOutside(true); //设置对话框的大小 view.setMinimumHeight((int) (ScreenSizeUtils.getInstance(this).getScreenHeight() * 0.23f)); Window dialogWindow = dialog.getWindow(); WindowManager.LayoutParams lp = dialogWindow.getAttributes(); lp.width = (int) (ScreenSizeUtils.getInstance(this).getScreenWidth() * 0.75f); lp.height = WindowManager.LayoutParams.WRAP_CONTENT; lp.gravity = Gravity.CENTER; dialogWindow.setAttributes(lp); cancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); confirm.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); } }); dialog.show(); }
