android中的对话框形式大致分为四种，分别是一般对话框形式，列表对话框形式，单选对话框形式，多选对话框形式

另外一种是登录对话框形式

下面一一对这几种对话框进行详细的讲解

1.一般对话框

buttonone.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(main.this);
builder.setPositiveButton("确定", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub }
});
builder.setNegativeButton("取消", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
builder.setNeutralButton("忽略", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub }
});
AlertDialog alertDialog = builder.create();
alertDialog.setTitle("删除提示");
alertDialog.setMessage("您确定要删除吗？");
alertDialog.show();
}
});

2.列表对话框

buttontwo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(main.this);
CharSequence[] items = { "确定", "忽略", "取消" };
builder.setItems(items, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
switch (which) {
case 0:
Toast.makeText(main.this, "你选择的是确定按钮",2000).show();
break;

case 1:
Toast.makeText(main.this, "你选择的是忽略按钮",2000).show();
break;
case 2:
Toast.makeText(main.this, "你选择的是取消按钮",2000).show();
break;
}
}
});
AlertDialog alertDialog = builder.create();
alertDialog.setIcon(R.drawable.icon);
alertDialog.setTitle("列表对话框");
// alertDialog.setMessage("请选择");不能添加此方法
alertDialog.show();
}
});

3.单选对话框

buttonthree.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(main.this);
CharSequence[] items = { "aa", "bb", "cc" };
builder.setSingleChoiceItems(items, -1, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
// dialog.dismiss();
switch (which) {
case 0:
Toast.makeText(main.this, "你选择的是aa按钮",2000).show();
dialog.dismiss();
break;

case 1:
Toast.makeText(main.this, "你选择的是bb按钮",2000).show();
dialog.dismiss();
break;
case 2:
Toast.makeText(main.this, "你选择的是cc按钮",2000).show();
dialog.dismiss();
break;
}
}
});
AlertDialog alertDialog = builder.create();
alertDialog.setIcon(R.drawable.icon);
alertDialog.setTitle("列表对话框");
// alertDialog.setMessage("请选择");不能添加此方法
alertDialog.show();

}
});

buttonfive.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder=new AlertDialog.Builder(main.this);
builder.setSingleChoiceItems(R.array.city, -1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
switch (which) {
case 0:
Toast.makeText(main.this, "你选择的是北京",2000).show();
dialog.dismiss();
break;
case 1:
Toast.makeText(main.this, "你选择的是上海",2000).show();
dialog.dismiss();
break;
case 2:
Toast.makeText(main.this, "你选择的是广州",2000).show();
dialog.dismiss();
break;

default:
break;
}
}
});
AlertDialog alertDialog=builder.create();
alertDialog.setIcon(R.drawable.icon);
alertDialog.setTitle("列表对话框");
alertDialog.show();
}
});

4.多选对话框

buttonfour.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
AlertDialog.Builder builder=new AlertDialog.Builder(main.this);
final CharSequence[] items={"跑步","上网","旅游","读书"};
builder.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() {

@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// TODO Auto-generated method stu

}
});

builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});

builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});

AlertDialog alertDialog=builder.create();
alertDialog.setIcon(R.drawable.icon);
alertDialog.setTitle("列表对话框");
alertDialog.show();
}
});

5.登录对话框

public class Main extends Activity {
private Button buttonone;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

buttonone=(Button)this.findViewById(R.id.buttononeid);
buttonone.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
final LinearLayout layout=(LinearLayout)LayoutInflater.from(Main.this).inflate(R.layout.login, null);
AlertDialog.Builder builder=new AlertDialog.Builder(Main.this);
builder.setView(layout);
builder.setPositiveButton("登陆", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
EditText edtText=(EditText)layout.findViewById(R.id.username);
Toast.makeText(Main.this, edtText.getText().toString(), 1).show();

main.this.showToast("正在登录，请稍后。。。");
}
});

builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}
});
AlertDialog alertDialog=builder.create();
alertDialog.setTitle("登录对话框");
alertDialog.show();
}
});
}
}
