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
