关于Android对话框简单实用方法总结

要显示一个对话框，首先需要在xx.xml下添加一个Button按钮，并添加一个对应id。

单次点击事件对话框：

 button.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                //定义对话框的步骤
                //1.获取buidlder对象
                final AlertDialog.Builder builder =new AlertDialog.Builder(MainActiviy.this);
                //2.通过调用builder对象的方法，设置对话框的标题，内容，图标，按钮
                builder.setMessage("这是一个简单的对话框");
                //3.通过bulider创建简单的对话框
                builder.create();
                //4.通过builder对象的show方法，显示对话框
                builder.show();

多事件对话框选择：

  builder.setMessage("你是一个简单的傻哥")

  .setTitle("对话框")
                    .setIcon(R.drawable.cat)
                    .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            button.setText("您点了确定");
                        }
                    })
                    .setNegativeButton("取消",null)
                    .create()
                    .show();

        }
    });
}

点击选择提示对话框：

 builder.setItems(new String[]{"红色", "黄色", "绿色"}, new DialogInterface.OnClickListener() {
                   @Override
                   public void onClick(DialogInterface dialog, int which) {
                       switch(which){
                            case 0:
                                button.setText("傻哥");
                               break
                            case 1:
                                button.setText("傻哥1");
                               break;
                           case 2:
                               button.setText("傻哥2");
                               break;

                       }

                   }
                })

  .setIcon(R.drawable.cat)
                    .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            button.setText("您点了确定");
                        }
                    })
                    .setNegativeButton("取消",null)
                    .create()
                    .show();

        }
    });
}

调用颜色变化：

  builder.setSingleChoiceItems(new String[]{"红色","黄色","绿色"},
                    1,new DialogInterface.OnClickListener(){

                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            switch (which){
                                case 0:
                                    button.setTextColor(getResources().getColor(R.color.colorAccent));
                                    break;
                                case 1:
                                    button.setTextColor(getResources().getColor(R.color.colorPrimary));
                                    break;
                                case 2:
                                    button.setTextColor(getResources().getColor(R.color.colorPrimaryDark));
                                    break;
                            }

                        }
                    })

                    .setTitle("对话框")
                    .setIcon(R.drawable.cat)
                    .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            button.setText("您点了确定");
                        }
                    })
                    .setNegativeButton("取消",null)
                    .create()
                    .show();

        }
    });
}

多选对话框

init();
    button.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v) {
            AlertDialog.Builder builder=new AlertDialog.Builder(Main20170326.this);
            final boolean[] checkeds={true,true,false};
            final String[] items =new String[]{"红色","黄色","蓝色"};
            builder.setMultiChoiceItems(new String[]{"红色","黄色","蓝色"}
                    , checkeds,new DialogInterface.OnMultiChoiceClickListener(){

                        @Override
                        public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                            String result="";
                            for(int i=0; i<checkeds.length;i++){
                                if(checkeds[i]){
                                    result +=items[i]+"";
                                }
                            }
                            textView.setText(result);
                        }
                    })
            .setTitle("多选对话框")
            .create()
            .show();
        }
    });
