Android 对话框(Dialog)大全详解及示例代码

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;
 }

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();

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();

 

new AlertDialog.Builder(this).setTitle("复选框").setMultiChoiceItems(
   new String[] { "Item1", "Item2" }, null, null)
   .setPositiveButton("确定", null)
   .setNegativeButton("取消", null).show();

 

new AlertDialog.Builder(this).setTitle("单选框").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("取消", null).show();

 

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