android复选框显示和隐藏

单击要显示linearlayout7、linearlayout8、linearlayout9的复选框时，linearlayout6中有一个复选框。否则我想隐藏这3个线性布局（7,8,9）

复选框

<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/checkbox1"
/>

XML

---

在

xml

布局中添加三个

复选框，就像对
复选框1
所做的那样，然后为它们指定id

  CheckBox checkbox=(CheckBox)findViewById(R.id.checkBoxInLayout6);

     public void addListenerOnChk() // for checkbox
        {

            checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
                    if(isChecked)
                    {
                        checkBoxInLayout7.setVisibility(View.VISIBLE);
                        checkBoxInLayout8.setVisibility(View.VISIBLE);
                        checkBoxInLayout9.setVisibility(View.VISIBLE);

                    }
                    else
                    {
                        checkBoxInLayout7.setVisibility(View.INVISIBLE);
                        checkBoxInLayout8.setVisibility(View.INVISIBLE);
                        checkBoxInLayout9.setVisibility(View.INVISIBLE);

                    }
                }
            });
        }

                    }
                }
            });
        }

这是解决办法

checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (isChecked){
                linearlayout7.setVisibility(View.VISIBLE);
                linearlayout8.setVisibility(View.VISIBLE);
                linearlayout9.setVisibility(View.VISIBLE);
            }else {
                linearlayout7.setVisibility(View.GONE);
                linearlayout8.setVisibility(View.GONE);
                linearlayout9.setVisibility(View.GONE);
            }
        }
    });

只是简单的代码。
很乐意帮忙
以下是解决方案

checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (isChecked){
                linearlayout7.setVisibility(View.VISIBLE);
                linearlayout8.setVisibility(View.VISIBLE);
                linearlayout9.setVisibility(View.VISIBLE);
            }else {
                linearlayout7.setVisibility(View.GONE);
                linearlayout8.setVisibility(View.GONE);
                linearlayout9.setVisibility(View.GONE);
            }
        }
    });

只是简单的代码。
很乐意帮助您试试这些：

 checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if(isChecked)
                {
                    ll7.setVisibility(View.VISIBLE);
                    ll8.setVisibility(View.VISIBLE);
                    ll9.setVisibility(View.VISIBLE);

                }
                else
                {
                    ll7.setVisibility(View.GONE);
                    ll8.setVisibility(View.GONE);
                    ll9.setVisibility(View.GONE);

                }
            }
        });

试试这些：

 checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if(isChecked)
                {
                    ll7.setVisibility(View.VISIBLE);
                    ll8.setVisibility(View.VISIBLE);
                    ll9.setVisibility(View.VISIBLE);

                }
                else
                {
                    ll7.setVisibility(View.GONE);
                    ll8.setVisibility(View.GONE);
                    ll9.setVisibility(View.GONE);

                }
            }
        });

试着简单一点

试着简单一点。
1.添加

android:onClick="onCheckboxClicked" 

属性，然后将下面的代码添加到.java文件中

public void onCheckboxClicked(View view) {
// Is the view now checked?
boolean checked = ((CheckBox) view).isChecked();

// Check which checkbox was clicked
switch(view.getId()) {
    case R.id.checkbox_meat:
        if (checked)
            showLayout789();
          //do things when checked
        else
            removeLayout789();
          // do things when unchecked
        break;

}
}

现在使用布局的id查找布局并设置其可见性

private void showLayout789(){
View v9 = findViewById(R.id.screen4layout9);
    v9.setVisibility(View.VISIBLE);
View v8 = findViewById(R.id.screen4layout8);
    v8.setVisibility(View.VISIBLE);
View v7 = findViewById(R.id.screen4layout7);
    v7.setVisibility(View.VISIBLE);
}

使不可见

 private void removeLayout789(){
View v9 = findViewById(R.id.screen4layout9);
    v9.setVisibility(View.GONE);
View v8 = findViewById(R.id.screen4layout8);
    v8.setVisibility(View.GONE);
View v7 = findViewById(R.id.screen4layout7);
    v7.setVisibility(View.GONE);
}

1.加入

属性，然后将下面的代码添加到.java文件中

public void onCheckboxClicked(View view) {
// Is the view now checked?
boolean checked = ((CheckBox) view).isChecked();

// Check which checkbox was clicked
switch(view.getId()) {
    case R.id.checkbox_meat:
        if (checked)
            showLayout789();
          //do things when checked
        else
            removeLayout789();
          // do things when unchecked
        break;

}
}

现在使用布局的id查找布局并设置其可见性

private void showLayout789(){
View v9 = findViewById(R.id.screen4layout9);
    v9.setVisibility(View.VISIBLE);
View v8 = findViewById(R.id.screen4layout8);
    v8.setVisibility(View.VISIBLE);
View v7 = findViewById(R.id.screen4layout7);
    v7.setVisibility(View.VISIBLE);
}

使不可见

 private void removeLayout789(){
View v9 = findViewById(R.id.screen4layout9);
    v9.setVisibility(View.GONE);
View v8 = findViewById(R.id.screen4layout8);
    v8.setVisibility(View.GONE);
View v7 = findViewById(R.id.screen4layout7);
    v7.setVisibility(View.GONE);
}

此外，你还需要默认隐藏布局的可见性。我认为如果你知道或编写android代码，这是非常容易的，那么你肯定知道如何在android中隐藏和显示任何视图。但是如果你不知道android开发，那么从一些对你来说很困难的地方选择这些代码，有任何答案解决了你的问题吗？如果是，请标记它。Thanks@JohnJoe非常感谢。工作正常。@Hareshchelana我是android新手：D。我知道代码是如何工作的，但对linearlayout不太确定。另外，你需要默认隐藏布局的可见性。我认为这很容易，如果你知道或编写android代码，那么你肯定知道如何在android中隐藏和显示任何视图，但如果你不知道android开发，那么选择这个从某些地方输入的代码对您来说很困难，有没有解决您的问题的答案？如果是，请标记它。Thanks@JohnJoe非常感谢。工作正常。@Hareshchelana我是android的新手：D。我知道代码是如何工作的，但对linearlayout不太清楚。谢谢你帮助我，谢谢你帮助我，谢谢你帮助我，谢谢你帮助我
