当我点击我想要显示linearlayout7,linearlayout8,linearlayout9的复选框时,我在linearlayout6中有一个复选框。否则我想隐藏这3个linearlayout(7,8,9)。

在checkboxes
布局中添加三个xml
,就像您为checkbox1
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);
}
}
});
}

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);
}
}
});
答案 2 :(得分:1)
CheckBox checkbox=(CheckBox)findViewById(R.id.checkbox1);
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);
}
}
});
轻松一试......

这是解决方案
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);
}
}
});
简单的代码。 很乐意提供帮助

1.增加
android:onClick="onCheckboxClicked"
将XML格式设置为CheckBox,然后在.java文件中添加以下代码
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;
}
}
现在使用他们的ID找到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);
}
设置隐身
private void showLayout789(){
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);
}
