更新[26-01-2016]：您可以按照此方式检查/取消选中动态创建的复选框。
在onCreate（Bundle bundle）{...}里面添加： 几点注意事项：
如果您使用以下内容，则需要为基本布局提供ID：
setContentView(R.layout.new_layout);
也就是说，当您使用layout xml设置ContentView时。
请记住，您可以为其他复合按钮而不是CheckBox使用类似的逻辑。
//Get Base Layout
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.base_layout);
//Create new CheckBox
CheckBox mainCheckBox = new CheckBox(this);
//Create a new ids.xml in values folder and add dummy id there. Than use that dummy id for dynamically created views
mainCheckBox.setId(R.id.main_cb);
//Give a name to it
mainCheckBox.setText(R.string.mainCB);
//Add it to Base layout
linearLayout.addView(mainCheckBox, 0);
//Create other CheckBoxes...
CheckBox[] checkBoxes = new CheckBox[5];
for (int i = 0; i < 5; i++) {
checkBoxes[i] = new CheckBox(this);
checkBoxes[i].setText(String.format(Locale.getDefault(), "Child CheckBox %d", i + 1));
checkBoxes[i].setId(i+101);
linearLayout.addView(checkBoxes[i], i+1);
}
//Creating each checkbox individually:
CheckBox checkBox = new CheckBox(this);
checkBox.setText("Child CheckBox 6");
//Either add an integer value
checkBox.setId(106);
/*
* Or else use a dummy id
* checkBox.setId(R.id.child_cb);
*/
linearLayout.addView(checkBox, 6);
//Set listener to main CheckBox
mainCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//Create an array of integer type to store all ids of child CBs
int[] ids = new int[] { 101, 102, 103, 104, 105, 106 };
/*
* You can also do
* int[] ids = new int[] { 101, 102, 103, 104, 105, R.id.child_cb };
*/
if(isChecked) {
Toast.makeText(getBaseContext(), "Checked", Toast.LENGTH_SHORT).show();
checkChildCBs(ids);
} else {
Toast.makeText(getBaseContext(), "Unchecked", Toast.LENGTH_SHORT).show();
unCheckChildCBs(ids);
}
}
});
检查所有CheckBoxes的方法
private void checkChildCBs(int[] ids) {
//Create CheckBox array of same size as that of ids
CheckBox[] checkBoxes = new CheckBox[ids.length];
//Run loop to check them
for (int i = 0; i < ids.length; i++) {
checkBoxes[i] = (CheckBox) findViewById(ids[i]);
checkBoxes[i].setChecked(true);
}
}
取消检查所有CheckBox的方法
private void unCheckChildCBs(int[] ids) {
//Create CheckBox array of same size as that of ids
CheckBox[] checkBoxes = new CheckBox[ids.length];
//Run loop to unCheck them
for (int i = 0; i < ids.length; i++) {
checkBoxes[i] = (CheckBox) findViewById(ids[i]);
checkBoxes[i].setChecked(false);
}
}
/res/values/ids.xml：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item type="id" name="main_cb" />
<item type="id" name="child_cb" />
</resources>
更新：您可以按照以下代码启用/禁用动态创建的CheckBoxPreferences。
在/ res / xml / directory中创建一个名为preferences.xml的新文件：
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android"
android:key="pref_screen">
</PreferenceScreen>
比onCreate（）中的PreferenceActivity：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Add preference xml file from /res/xml/
addPreferencesFromResource(R.xml.preferences);
}
现在我们将动态创建CheckBoxPreference：
// Get PreferenceScreen using the key as stated in preferences.xml
PreferenceScreen prefScreen = (PreferenceScreen) findPreference("pref_screen");
// Now create a CheckBoxPreference array. The size of the array will be the number of required CheckBoxPreferences.
CheckBoxPreference[] cbPrefs = new CheckBoxPreference[5]; // You can set any number you want. This will allow you to create 5 CheckBoxPreferences.
// Run loop to create CheckBoxPreferences and add them to the PreferenceScreen.
for (int i = 0; i < cbPrefs.length; i++) {
cbPrefs[i] = new CheckBoxPreference(getActivity());
cbPrefs[i].setTitle("Dynamically created multiple Pref " + (i+1));
cbPrefs[i].setKey("multiple_dynamic_pref_key_" + (i+1));
prefScreen.addPreference(cbPrefs[i]); // Adds the newly created CheckBoxPreference to the PreferenceScreen
}
/*
IF you want, you can also create new CheckBoxPreference individually like this :
cbPrefs[0] = new CheckBoxPreference(getActivity());
cbPrefs[0].setTitle("My Preference");
cbPrefs[0].setKey("my_pref_key");
prefScreen.addPreference(cbPrefs[0]);
cbPrefs[1] = new CheckBoxPreference(getActivity());
cbPrefs[1].setTitle("Some Name");
cbPrefs[1].setKey("some_pref_key");
prefScreen.addPreference(cbPrefs[1]);
and so on and so forth...
*/
// Now create and add a Preference to the PreferenceScreen
Preference preference = new Preference(getActivity());
preference.setTitle("Preference");
prefScreen.addPreference(preference);
// Now set onPreferenceClickListener to newly created preference.
preference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference preference) {
String[] prefKeys = new String[] {"multiple_dynamic_pref_key_1", "multiple_dynamic_pref_key_2",
"multiple_dynamic_pref_key_3", "multiple_dynamic_pref_key_4",
"multiple_dynamic_pref_key_5"};
changePrefsState(prefKeys, cbPrefs);
return false;
}
});
最后你的onCreate（）将如下所示：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Add preference xml file from /res/xml/
addPreferencesFromResource(R.xml.preferences);
// Get PreferenceScreen using the key as stated in preferences.xml
PreferenceScreen prefScreen = (PreferenceScreen) findPreference("pref_screen");
// Now create a CheckBoxPreference array. The size of the array will be the number of required CheckBoxPreferences.
CheckBoxPreference[] cbPrefs = new CheckBoxPreference[5]; // You can set any number you want. This will allow you to create 5 CheckBoxPreferences.
// Run loop to create CheckBoxPreferences and add them to the PreferenceScreen.
for (int i = 0; i < cbPrefs.length; i++) {
cbPrefs[i] = new CheckBoxPreference(getActivity());
cbPrefs[i].setTitle("Dynamically created multiple Pref " + (i+1));
cbPrefs[i].setKey("multiple_dynamic_pref_key_" + (i+1));
prefScreen.addPreference(cbPrefs[i]); // Adds the newly created CheckBoxPreference to the PreferenceScreen
}
// Now create and add a Preference to the PreferenceScreen
Preference preference = new Preference(getActivity());
preference.setTitle("Preference");
PreferenceScreen.addPreference(preference);
// Now set onPreferenceClickListener to newly created preference.
preference.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference preference) {
String[] prefKeys = new String[] {"multiple_dynamic_pref_key_1", "multiple_dynamic_pref_key_2",
"multiple_dynamic_pref_key_3", "multiple_dynamic_pref_key_4",
"multiple_dynamic_pref_key_5"};
changePrefsState(prefKeys, cbPrefs);
return false;
}
});
}
// This function is called when you click on preference to check/uncheck CheckBoxPrefs.
private void changePrefsState(String[] prefKeys, CheckBoxPreference[] checkBoxPreferences) {
try {
for (int i = 0; i < prefKeys.length; i++) {
checkBoxPreferences[i] = (CheckBoxPreference) findPreference(prefKeys[i]);
// Check if CheckBozPreference is Checked. If yes than unCheck it else Check it
if (checkBoxPreferences[i].isChecked())
checkBoxPreferences[i].setChecked(false);
else
checkBoxPreferences[i].setChecked(true);
}
} catch(Exception e) {
Toast.makeText(getActivity().getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
旧：
private void someFunction() {
String[] prefKeys = new String[] {"pref_key_1", "pref_key_2", "pref_key_3", "pref_key_4", "pref_key_5"};
CheckBoxPreference[] cbPrefs = new CheckBoxPreference[prefKeys.length];
changePrefsState(prefKeys, cbPrefs);
}
private void changePrefsState(String[] prefKeys, CheckBoxPreference[] checkBoxPreferences) {
try {
for (int i = 0; i < prefKeys.length; i++) {
checkBoxPreferences[i] = (CheckBoxPreference) findPreference(prefKeys[i]);
// Check if CheckBozPreference is Checked. If yes than unCheck it else Check it
if (checkBoxPreferences[i].isChecked())
checkBoxPreferences[i].setChecked(false);
else
checkBoxPreferences[i].setChecked(true);
}
} catch(Exception e) {
Toast.makeText(getActivity().getBaseContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
以上示例适用于动态创建的首选项和XML定义的首选项。 你只需要传递密钥和pref类型。 您可以为不同的首选项类型创建不同的changePrefsState（arg1，arg2）{...}。

主复选框，用于选中全部复选框。
CheckBox tvchkall = new CheckBox(ItemCodeRelease.this);
tvchkall.setId(101);
tvchkall.setOnClickListener(getOnClickDoSomething(tvchkall));
listner，检查所有复选框是动态创建者。
View.OnClickListener getOnClickDoSomething(final CheckBox chk) {
return new View.OnClickListener() {
public void onClick(View v) {
if (chk.getId() == 101) {
if (chk.isChecked()) {
for (int a = 1; a < tblItemDetail.getChildCount(); a++) {
itemContainer[a][6] = "Y";
CheckBox cb1 = (CheckBox) ((TableRow) tblItemDetail.getChildAt(a)).getChildAt(1);
cb1.setChecked(true);
}
} else {
for (int a = 1; a < tblItemDetail.getChildCount(); a++) {
itemContainer[a][6] = "N";
CheckBox cb11 = (CheckBox) ((TableRow) tblItemDetail.getChildAt(a)).getChildAt(1);
}
}
} else {
if (chk.isChecked()) {
for (int a = 0; a < itemContainer.length; a++) {
for (int b = 0; b < itemContainer[a].length; b++) {
if (a == chk.getId()) {
itemContainer[a][6] = "Y";
}
}
}
} else {
for (int a = 0; a < itemContainer.length; a++) {
for (int b = 0; b < itemContainer[a].length; b++) {
if (a == chk.getId()) {
itemContainer[a][6] = "N";
}
}
}
}
}
}
};
}
