如何检查android

Question

你好我是android的初学者。我在我的项目中使用了四个复选框。我希望在复选框3和4未选中状态后调用一个方法。如何编写该代码请帮助我。

提前致谢。

class myCheckBoxChnageClicker implements CompoundButton.OnCheckedChangeListener {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            // Is the view now checked?
            boolean checked = ((CheckBox) buttonView).isChecked();


            // Check which checkbox was clicked
            switch(buttonView.getId()) {

                case R.id.t3_check:

                    if (checked) {



                    } else {


                    }

                    break;

                case R.id.t4_check:

                    if (checked) {



                    } else {



                    }

                    break;

                case R.id.tsh_check:

                    if (checked) {



                    } else {


                    }

                    break;

                case R.id.weight_check:

                    if(checked) {



                    } else {



                    }

                    break;
                default:

            }







        }

        public void showTextNotification(String msgToDisplay) {


            if ((msgToDisplay.equals("Tsh_Check") && msgToDisplay.equals("Weight_Check"))) {

                Toast.makeText(getApplicationContext(), "match", Toast.LENGTH_SHORT).show();

            } else {


            }


        }
    }

您好这是我的代码，我希望在3和 4复选框未选中状态时调用showTextNotification()方法。

Answer 1

您可以在复选框上调用isChecked（）来获取其状态。

Answer 2

checkBox1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
            if (checkBox2.isChecked() && isChecked) {
                // Perform task
            }
        }
    });

    checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
            if (checkBox1.isChecked() && isChecked) {
                // Perform task
            }
        }
    });

Answer 3

试试这个。

 final boolean Check_three = false;
 final boolean Check_foure  = false;

        class myCheckBoxChnageClicker implements CompoundButton.OnCheckedChangeListener {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                // Is the view now checked?
                boolean checked = ((CheckBox) buttonView).isChecked();


                // Check which checkbox was clicked
                switch(buttonView.getId()) {

                    case R.id.t3_check:

                        if (checked) {
                            Check_three = true;

                            if (Check_three == true && Check_foure == true)
                            {
                                showTextNotification("printmeaage");  
                            }


                        } else {
                            Check_three = false;

                        }

                        break;

                    case R.id.t4_check:

                        if (checked) {

                            Check_foure = true;
                            if (Check_three == true && Check_foure == true)
                            {
                                showTextNotification("printmeaage");
                            }

                        } else {

                            Check_foure = false;

                        }

                        break;

                    case R.id.tsh_check:

                        if (checked) {



                        } else {


                        }

                        break;

                    case R.id.weight_check:

                        if(checked) {



                        } else {



                        }

                        break;
                    default:

                }


            }
