目标
点击Faculty弹出院系单选对话框，将选择的内容显示在EditText中
Faculty是一个Edittext控件。
1,设置EditText属性
使用以下两句设置EditText为不可输入且不可弹出输入法
android:cursorVisible="false"android:editable="false"text="" android:id="@+id/etFaculty" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/etBirthday" android:cursorVisible="false" android:editable="false" android:hint="Faculty" /> 2，设置EditText的点击事件，使用setOnTouchListener
private final static int FACULTY_DIA = 2;private EditText etFaculty;@Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_personal_info); etFaculty = (EditText) findViewById(R.id.etFaculty); etFaculty.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub showDialog(FACULTY_DIA); return false; } });3，创建一个院系名的array资源 “faculty”
4，创建单选对话框
protected Dialog onCreateDialog(int id) { Dialog dialog = null; switch (id) { case FACULTY_DIA: Builder builder1 = new android.app.AlertDialog.Builder(this); // 设置对话框的图标 builder.setIcon(R.drawable.header); // 设置对话框的标题 Builder setTitle1 = builder1.setTitle("Faculty"); builder1.setSingleChoiceItems(R.array.faculty, 0, new OnClickListener() { public void onClick(DialogInterface dialog, int which) { String faculty = getResources().getStringArray(R.array.faculty)[which]; etFaculty.setTextSize(15); etFaculty.setText(faculty); } }); // 添加一个确定按钮 builder1.setPositiveButton(" OK ", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); // 创建一个单选按钮对话框 dialog = builder1.create(); break;}5，修改对话框的字体大小
在styles.xml定义对话框字体大小：
style> <style name="dialog" parent="@android:style/Theme.Dialog"> <item name="android:textSize">15spitem> style>加入后styles.xml的内容如下所示：
<resources> <style name="AppBaseTheme" parent="android:Theme.Light"> -- Theme customizations available in newer API levels can go in res/values-vXX/styles.xml, while customizations related to backward-compatibility can go here. --> style> <style name="AppTheme" parent="AppBaseTheme"> -- All customizations that are NOT specific to a particular API-level can go here. --> style> <style name="dialog" parent="@android:style/Theme.Dialog"> <item name="android:textSize">15spitem> style>resources>修改创建单选对话框的代码：
case FACULTY_DIA: // Dialog dialog = null; ContextThemeWrapper contextThemeWrapper = new ContextThemeWrapper(this, R.style.dialog); Builder builder1 = new AlertDialog.Builder(contextThemeWrapper); // Builder builder1 = new android.app.AlertDialog.Builder(this); // 设置对话框的图标 // builder.setIcon(R.drawable.header); // 设置对话框的标题 Builder setTitle1 = builder1.setTitle("Faculty"); // 0: 默认第一个单选按钮被选中 builder1.setSingleChoiceItems(R.array.faculty, 0, new OnClickListener() { public void onClick(DialogInterface dialog, int which) { String faculty = getResources().getStringArray(R.array.faculty)[which]; etFaculty.setTextSize(15); etFaculty.setText(faculty); } }); // 添加一个确定按钮 builder1.setPositiveButton(" OK ", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }); // 创建一个单选按钮对话框 dialog = builder1.create(); break;更多相关文章
