以下是我的布局xmls。现在我们在布局中有一个有限数量（七个）的复选框（listitem.xml）。我们将它添加到线性布局中。

但是根据新要求，我们需要动态添加复选框。就像需要从API调用中获取选项并将其转换为视图中的复选框一样。我花了很多时间。有人可以建议一种方法来解决这个问题。
我们的布局应该是这样的。在列表视图中，我们显示员工详细信息，并且对于每个员工记录，应从API调用或数据库加载限定条件。

LinearLayout featuresTable = (LinearLayout) findViewById(R.id.failure_reasonslist);
// use loop

动态添加CheckBox
LinearLayout my_layout = (LinearLayout)findViewById(R.id.my_layout);
// Add Checkbox Dynamically
CheckBox checkBox = new CheckBox(mContext);
checkBox.setText(ETnewcheckbox.getText().toString()+"");
checkBox.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
String msg = "You have " + (isChecked ? "checked" : "unchecked") + " this Check it Checkbox.";
Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
}
});
// Add Checkbox to LinearLayout
if (my_layout != null) {
my_layout.addView(checkBox);
}
试试这个。
LinearLayout lLayout = (LinearLayout)findViewById(R.id.yourMainLayout);
CheckBox checkBox = new CheckBox(this); // Here you will create CheckBox as many number of Checkbox you want.
lLayout.addView(checkBox); // Here you have to add this CheckBox to your layout.
祝好运。
