android中Dialog的使用

各种Dialog的使用：

public class MainActivity extends Activity {

//单选项的数组
private String[] singleItems=new String[]{"上网","游戏","看电影"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}


public void nomaldialog(View view){
// AlertDialog.Builder builder=new Builder(this);
// //设置对话框的相关参数
// builder.setTitle("普通对话框");
// builder.setIcon(R.drawable.ic_launcher);
// builder.setMessage("信息");
// //创建对话框对象
// AlertDialog dialog=builder.create();

AlertDialog dialog=new Builder(this)
.setTitle("普通对话框")
.setIcon(R.drawable.ic_launcher)
.setMessage("信息")
.create();
//显示
dialog.show();
}

public void buttondialog(View view){
AlertDialog dialog=new Builder(this)
.setIcon(R.drawable.ic_launcher)
.setTitle("带按钮的对话框")
.setMessage("消息")
.setPositiveButton("确认", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "确认按钮己被点击", Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("取消", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "取消按钮己被点击", Toast.LENGTH_LONG).show();
}
})
.setNeutralButton("忽略", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "忽略按钮己被点击", Toast.LENGTH_LONG).show();
}
})
.create();
dialog.show();
}

public void singledialog(View view){

AlertDialog dialog=new Builder(this)
.setTitle("选择爱好")
.setIcon(R.drawable.ic_launcher)
.setSingleChoiceItems(singleItems, -1, new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(MainActivity.this, "选定的爱好："+singleItems[which], Toast.LENGTH_LONG).show();
dialog.cancel();
}
})
.create();
dialog.show();
}

public void multidialog(View view){
AlertDialog dialog=new Builder(this)
.setTitle("选择爱好")
.setIcon(R.drawable.ic_launcher)
.setCancelable(false)
.setMultiChoiceItems(singleItems, new boolean[]{true,false,false}, new OnMultiChoiceClickListener() {

@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
//判断当前点击的选项是否被选定了
if (isChecked) {
Toast.makeText(MainActivity.this, singleItems[which]+"被选定了", Toast.LENGTH_SHORT).show();
}
}
})
.setPositiveButton("设置", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
//关闭对话框
dialog.dismiss();
}
})
.create();
dialog.show();
}

}
