第二十三天 TextView、Button

TextView

textViewPhone.setTextColor(Color.BLUE);//设置文本颜色textViewPhone.setAutoLinkMask(Linkify.PHONE_NUMBERS);//拨打电话(android:autoLink="phone")//上网(android:autoLink="web")textViewPhone.setText("拨打电话：[phone]");//要写在setAutoLinkMask一句的后面

 textViewPrice=(TextView)findViewById(R.id.textViewPrice); textViewPrice.setPaintFlags(Paint.STRIKE_THRU_TEXT_FLAG);//在text上加上中划线

 textViewImg=(TextView)findViewById(R.id.textView_img);        String text="我是一个<font color='#ff0000'>富文本</font>,然后末尾加一个图标<img src='a_main_icon08'/>";        Html.ImageGetter getter=new Html.ImageGetter() {            @Override            public Drawable getDrawable(String source) {                int id=R.mipmap.ic_launcher;                Class clazz=R.mipmap.class;                try {                    Field field = clazz.getDeclaredField(source);                    id=field.getInt(clazz);                } catch (IllegalAccessException e) {                    e.printStackTrace();                }catch (NoSuchFieldException e) {                    e.printStackTrace();                }                Drawable drawable=getResources().getDrawable(id);                drawable.setBounds(0,0,drawable.getIntrinsicHeight(),drawable.getIntrinsicWidth());                return drawable;            }        };        Spanned spanned=Html.fromHtml(text,getter,null);        textViewImg.setText(spanned);

文本滚动 界面小设计

登录小界面

android:hint=”请输入密码” （EditText中的提示语）
password=true（密码不可见）

editText_password=(EditText)findViewById(R.id.editText_password);Button button=(Button)findViewById(R.id.button);button.setOnClickListener(new View.OnClickListener() {     @Override     public void onClick(View v) {     editText_password.setTransformationMethod(null);     } });//设置密码可见

Button

ninepatch:上左代表拉伸、下右代表内容

当按下按钮时，按钮变成其他颜色(使用SDK下tools中的draw9patch工具编辑图片)

drawable

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"><item android:drawable="@mipmap/back" android:state_pressed="true"/>    <item android:drawable="@mipmap/picture9" /></selector>

Button

 <Button           android:layout_width="match_parent"           android:layout_height="wrap_content"           android:layout_gravity="center_horizontal"           android:text="密码可见"           android:id="@+id/button"android:background="@drawable/back_drawable"/>

RadioButton

public class MainActivity extends Activity {    private RadioGroup mRadioGroup;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.radio_layout);        mRadioGroup= (RadioGroup) findViewById(R.id.radioGroup);        mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {            @Override            public void onCheckedChanged(RadioGroup group, int checkedId) {                RadioButton rb= (RadioButton) findViewById(checkedId);                Log.d("sex","您的性别是："+rb.getText());            }        });    }}
