Android——四种AterDialog

本经验将分别介绍Android里面的四种AlertDialog分别是：显示带中立，取消，确定的提示框、 获取带列表的对话框按钮、获取带单选列表的对话框按、获取显示带多选项的对话框。此经验介绍获取显示带多选项的对话框

Android studio或者Eclipse

首先我们在界面布局上面布局四个按钮

然后我们在代码中关联这四个按钮

Button button3=(Button)findViewById(R.id.button3);

Button button4=(Button)findViewById(R.id.button4);

 Button button5=(Button)findViewById(R.id.button5);

 Button button6=(Button)findViewById(R.id.button6);

然后分别加入触发事件：

//获取带列表的对话框按钮

        button4.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                final String[] iterms=new String[]{"run","badminton","football","pingpang","gymnastics","tennis","more..."};

                AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this);

                //builder.setIcon(R.drawable.desert);

                builder.setTitle("Choose your favable sport project:");

                builder.setItems(iterms,new DialogInterface.OnClickListener() {

                    @Override

                    public void onClick(DialogInterface dialog, int which) {

                        Toast.makeText(getApplicationContext(),"You choosed "+iterms[which],Toast.LENGTH_LONG).show();

                    }

                });

                builder.create().show();//创建对话框并显示

            }

        });

        //获取带单选列表的对话框按钮

        button5.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                final String[] iterms=new String[]{"standard","silent","meeting","outdoor","offline"};

                AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this);

                //builder.setIcon(R.drawable.desert);

                builder.setTitle("Choose your favable contextual model:");

                builder.setSingleChoiceItems(iterms, 0, new DialogInterface.OnClickListener() {

                    @Override

                    public void onClick(DialogInterface dialog, int which) {

                        Toast.makeText(getApplicationContext(), "You choosed " + iterms[which], Toast.LENGTH_LONG).show();

                    }

                });

                builder.create().show();//创建对话框并显示

            }

        });

        //获取显示带多选项的对话框

        button6.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                checkedItems=new boolean[]{false,true,false,true,false};

                items=new String[]{"Plants vs Zombies","Angry Birds","popodino","Happy Farm","Super Mario"};

                //显示带单选列表的对话框

                AlertDialog.Builder builder=new AlertDialog.Builder(getApplicationContext());

                //builder.setIcon(R.drawable.desert);

                builder.setTitle("Choose your favorable Game:");

                builder.setMultiChoiceItems(items,checkedItems,new DialogInterface.OnMultiChoiceClickListener() {

                    @Override

                    public void onClick(DialogInterface dialog, int which, boolean isChecked) {

                        checkedItems[which]=isChecked;

                    }

                });

                //为对话框添加"确定按钮"

                builder.setPositiveButton("confirm",new DialogInterface.OnClickListener() {

                    @Override

                    public void onClick(DialogInterface dialog, int which) {

                        String result="";

                        for(int i=0;i<checkedItems.length;i++){

                            if(checkedItems[i]==true){

                                result+=items[i]+",";

                            }

                        }

                        if(result.equals("")==false){

                            result=result.substring(0,result.length()-1);

                            Toast.makeText(MainActivity.this,"You  choosed "+result,Toast.LENGTH_LONG).show();

                        }

                    }

                });

                builder.create().show();

            }

        });

运行结果如下
