第二十三天 TextView、Button

TextView

textViewPhone.setTextColor(Color.BLUE);//設置文本顏色
textViewPhone.setAutoLinkMask(Linkify.PHONE_NUMBERS);//撥打電話(android:autoLink="phone")
//上網(android:autoLink="web")
textViewPhone.setText("撥打電話：[phone]");//要寫在setAutoLinkMask一句的後面

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

 textViewImg=(TextView)findViewById(R.id.textView_img);
        String text="我是一個<font color='#ff0000'>富文本</font>,然後末尾加一個圖標<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);

登錄小界面

android:hint=”請輸入密碼” （EditText中的提示語）
password=true（密碼不可見）

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);
     }
 });//設置密碼可見

Button

ninepatch:上左代表拉伸、下右代表內容

當按下按鈕時，按鈕變成其他顏色(使用SDK下tools中的draw9patch工具編輯圖片)

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" />

           android:text="密碼可見"
           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);

                Log.d("sex","您的性別是："+rb.getText());
            }
