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
