Android dialog对话框的使用方法有哪些，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

在Android开发中，我们经常会需要在Android界面上弹出一些对话框，比如询问用户或者让用户选择。这些功能我们叫它Android Dialog对话框，在我们使用Android的过程中，我归纳了一下，Android Dialog的类型无非也就7种，下面我分别向大家介绍这7种Android Dialog对话框的使用方法，希望对大家能有所帮助。

1.该效果是当按返回按钮时弹出一个提示，来确保无误操作，采用常见的对话框样式。

创建dialog对话框方法代码如下：

protected void dialog() { AlertDialog.Builder builder = new Builder(Main.this); builder.setMessage("确认退出吗？"); builder.setTitle("提示"); builder.setPositiveButton("确认", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); Main.this.finish(); } }); builder.setNegativeButton("取消", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); builder.create().show(); }

在onKeyDown(int keyCode, KeyEvent event)方法中调用此方法

public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) { dialog(); } return false; }

2..改变了对话框的图表，添加了三个按钮

创建dialog的方法代码如下：

Dialog dialog = new AlertDialog.Builder(this).setIcon( android.R.drawable.btn_star).setTitle("喜好调查").setMessage( "你喜欢李连杰的电影吗？").setPositiveButton("很喜欢", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(Main.this, "我很喜欢他的电影。", Toast.LENGTH_LONG).show(); } }).setNegativeButton("不喜欢", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(Main.this, "我不喜欢他的电影。", Toast.LENGTH_LONG) .show(); } }).setNeutralButton("一般", new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(Main.this, "谈不上喜欢不喜欢。", Toast.LENGTH_LONG) .show(); } }).create(); dialog.show();

3.信息内容是一个简单的View类型

创建dialog方法的代码如下：

new AlertDialog.Builder(this).setTitle("请输入").setIcon( android.R.drawable.ic_dialog_info).setView( new EditText(this)).setPositiveButton("确定", null) .setNegativeButton("取消", null).show();

4.信息内容是一组单选框

The code to create the dialog method is as follows:

new AlertDialog.Builder(this).setTitle("Checkbox").setMultiChoiceItems( new String[] { "Item1", "Item2" }, null, null) .setPositiveButton("OK", null) .setNegativeButton("Cancel", null).show();

5. The message content is a set of boxes

The code to create the dialog method is as follows:

new AlertDialog.Builder(this).setTitle("Radio Box").setIcon( android.R.drawable.ic_dialog_info).setSingleChoiceItems( new String[] { "Item1", "Item2" }, 0, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }).setNegativeButton("Cancel", null).show();

6. Information content is a simple set of list items

The method code for creating a dialog is as follows:

new AlertDialog.Builder(this).setTitle("ListBox").setItems( new String[] { "Item1", "Item2" }, null).setNegativeButton( "OK", null).show();

7. Message content is a custom layout

The dialog layout file code is as follows:

The code to create the dialog method is as follows:

LayoutInflater inflater = getLayoutInflater(); View layout = inflater.inflate(R.layout.dialog, (ViewGroup) findViewById(R.id.dialog)); new AlertDialog.Builder(this).setTitle("Custom Layout").setView(layout) .setPositiveButton("OK", null) .setNegativeButton("Cancel", null).show(); Did it help you to read all of the above?
