Question

在我的应用程序中，我将Frame Layout可见性设置为GONE，我想在单击复选框时显示Frame布局。是否有可能将其设置为VISIBLE？

});

Answer 1

尝试这种方式它会帮助你

private int checkedBoxs = 0;
private final CheckBox.OnCheckedChangeListener listener = 
    new OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (isChecked) {
                status.set(position, true);
                checkedBoxs++;
                if (layout.getVisibility() == View.GONE)
                    layout.setVisibility(View.VISIBLE);
            } else {
                status.set(position, false);
                checkedBoxs--;
                if (checkedBoxs == 0)
                    layout.setVisibility(View.GONE);
            }
        }
    };

Answer 2

是..

ch = (CheckBox)findViewById(R.id.checkbox);              
ch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
        if(isChecked){
            framelayout.setVisibility(View.VISIBLE);//framelayout is your layout,initially set GONE.
        }
    }
  });

Answer 3

也许是因为你的框架布局中的视图可见性也消失了。

尝试以下代码

    checkBoxYes = (CheckBox)findViewById(R.id.checkBoxYes);
    ViewGroup frameLayout = (ViewGroup)findViewById(R.id.frameLayout)
    checkBoxYes.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked){
        frameLayout.setVisibility(View.VISIBLE);
         int count = frameLayout.getChildCount();
    for (int i = 0; i < count; i++) {
        View view = frameLayout.getChildAt(i);
        view.setVisibility(View.VISIBLE);
    }
    }
}

}）;

确保将frameLayout强制转换为ViewGroup。
