Android中AlertDialog的六种创建方式

　　// 创建构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// 设置参数
builder.setTitle("请做出选择").setIcon(R.drawable.ic_launcher)
.setMessage("凤姐美不美")
.setPositiveButton("美", new OnClickListener() {// 积极
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "恭喜你打错了", 0)
.show();
}
}).setNegativeButton("不美", new OnClickListener() {// 消极
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "恭喜你答对了", 0)
.show();
}
}).setNeutralButton("不知道", new OnClickListener() {// 中间级
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "你瞎啊", 0)
.show();
}
});
builder.create().show();

　　// 创建数据
final String[] items = new String[] { "北京", "上海", "广州", "深圳" };
// 创建对话框构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// 设置参数
builder.setIcon(R.drawable.ic_launcher).setTitle("提示")
.setItems(items, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, items[which],
Toast.LENGTH_SHORT).show();
}
});
builder.create().show();

// 创建数据
final String[] items = new String[] { "北京", "上海", "广州", "深圳" };
// 创建对话框构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// 设置参数
builder.setIcon(R.drawable.ic_launcher).setTitle("提示")
.setSingleChoiceItems(items, 0, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, items[which],
Toast.LENGTH_SHORT).show();
}
});
builder.create().show();

// 创建数据
final String[] items = new String[] { "北京", "上海", "广州", "深圳" };
// 创建对话框构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.ic_launcher)
.setTitle("提示")
.setMultiChoiceItems(items,
new boolean[] { true, true, false, false, false },
new OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which, boolean isChecked) {
// TODO Auto-generated method stub
if (isChecked) {
Toast.makeText(MainActivity.this,
items[which], 0).show();
}
}
});
builder.create().show();

　// 创建数据
final String[] items = new String[] { "北京", "上海", "广州", "深圳" };
// 创建对话框构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("提示")
.setIcon(R.drawable.ic_launcher)
.setAdapter(
new ArrayAdapter(MainActivity.this,
R.layout.item, R.id.tv, items),
new OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, items[which],
0).show();
}
});
builder.create().show();

　// 创建对话框构建器
AlertDialog.Builder builder = new AlertDialog.Builder(this);
// 获取布局
View view2 = View.inflate(MainActivity.this, R.layout.login, null);
// 获取布局中的控件
final EditText username = (EditText) view2.findViewById(R.id.username);
final EditText password = (EditText) view2.findViewById(R.id.password);
final Button button = (Button) view2.findViewById(R.id.btn_login);
// 设置参数
builder.setTitle("Login").setIcon(R.drawable.ic_launcher)
.setView(view2);
// 创建对话框
final AlertDialog alertDialog = builder.create();
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String uname = username.getText().toString().trim();
String psd = password.getText().toString().trim();
if (uname.equals("zcl") && psd.equals("123456")) {
Toast.makeText(MainActivity.this, "登录成功", 0).show();
}
Toast.makeText(MainActivity.this, "登录失败", 0).show();
alertDialog.dismiss();// 对话框消失
}
});
alertDialog.show();
