[1]textview加上划线

textview加下划线
如果是在资源文件里，可以这样写

<resources>
    <string name="hello"><u>phone: 1390123456</u></string>
    <string name="app_name">MyLink</string>
</resources>

如果是代码这样写.

TextView textView = (TextView)findViewById(R.id.testView); 
textView.setText(Html.fromHtml("<u>"+"hahaha"+"</u>"));

这个是eoe社区的人回答的，我还没测试，有空试试~

widget中只能使用前者，后者不可以；activity两种方式都能用。

onActivityResult传值的使用

有时候在群里加入的新人总会喜欢问一些过去的问题有时候不想回答是因为回答的次数多了

不回答又打击人的积极性谁让自己接触的早呢为了省劲还是把简单的东西作为指导篇吧

多个activity之间的传值其实就是onActivityResult，然后别忘了还有一个action的问题就是在主xml中添加自己的action以便于识别，最后次activity别忘了finansh。

public class Wizard extends Activity {

    private TextView step1result, step2result, step3result;

    public static final String INTENT_STEP1 = "com.novoda.STEP1";
    public static final String INTENT_STEP2 = "com.novoda.STEP2";
    public static final String INTENT_STEP3 = "com.novoda.STEP3";

    private static final int STEP1 = 1;
    private static final int STEP2 = 2;
    private static final int STEP3 = 3;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wizard);
        
        this.step1result = (TextView)findViewById(R.id.step1result);
        this.step2result = (TextView)findViewById(R.id.step2result);
        this.step3result = (TextView)findViewById(R.id.step3result);  
        
        startActivityForResult(new Intent(Wizard.INTENT_STEP1), STEP1);        
    }
    
    
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case STEP1:
                this.step1result.setText(data.getStringExtra("STEP1RESULT"));
                startActivityForResult(new Intent(Wizard.INTENT_STEP2), STEP2);    
                break;
            case STEP2:
                this.step2result.setText(data.getStringExtra("STEP2RESULT"));
                startActivityForResult(new Intent(Wizard.INTENT_STEP3), STEP3);    
                break;
            case STEP3:
                this.step3result.setText(data.getStringExtra("STEP3RESULT"));
                break;
        }
    }
}

public class Step1 extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.step1);

        Button nextStep = (Button)findViewById(R.id.goto2);
        nextStep.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent it = new Intent();
                it.putExtra("STEP1RESULT", ((EditText)findViewById(R.id.step1value)).getText()
                        .toString());
                setResult(Activity.RESULT_OK, it);
                finish();
            }
        });
    }
}

后面的step2 step3都是一样的了

然后还有主xml

<application android:icon="@drawable/icon" android:label="@string/app_name">
		<activity android:name=".Wizard" android:label="@string/app_name">
			<intent-filter>
				<action android:name="android.intent.action.MAIN" />
				<category android:name="android.intent.category.LAUNCHER" />
			</intent-filter>
		</activity>

		<activity android:name=".Step1" android:label="Step1">
			<intent-filter>
				<action android:name="com.novoda.STEP1" />
				<category android:name="android.intent.category.DEFAULT" />
			</intent-filter>
		</activity>

		<activity android:name=".Step2" android:label="Step2">
			<intent-filter>
				<action android:name="com.novoda.STEP2" />
				<category android:name="android.intent.category.DEFAULT" />
			</intent-filter>
		</activity>

		<activity android:name=".Step3" android:label="Step3">
			<intent-filter>
				<action android:name="com.novoda.STEP3" />
				<category android:name="android.intent.category.DEFAULT" />
			</intent-filter>
		</activity>
	</application>
	<uses-sdk android:minSdkVersion="7" />
</manifest>

animation-list旋转的地球以及Timer的使用

用到animation-list其实就是帧叠加，通常要注意两个问题

1.一般布局要用在frameLayout

2.它呢一般作为背景然后在取出来

public class EarthAnimationActivity extends Activity {

    private static final String TAG = "EarthAnimationActivity";

	protected static final int FORWARD = 0;
	protected static final int REVERSE = 1;

	private Button earthButton;

	private AnimationDrawable earthButtonAnimation;

	protected int direction;

	
	/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main);

        earthButton = (Button) findViewById(R.id.earth_button);
        earthButtonAnimation = (AnimationDrawable) earthButton.getBackground();
        direction = FORWARD;
        
        earthButton.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				if ( ! earthButtonAnimation.isRunning() ) {
					earthButtonAnimation.start();
					earthButton.setText(R.string.click_me_to_stop);
				}
				else {
					earthButtonAnimation.stop();
					int resId = R.anim.earth_animation_rev;
					if ( direction == FORWARD ) {
						direction = REVERSE;
					}
					else {
						resId = R.anim.earth_animation;
						direction = FORWARD;
					}
					earthButton.setBackgroundResource(resId);
					earthButtonAnimation = (AnimationDrawable) earthButton.getBackground();
					earthButton.setText(R.string.click_me_to_start);
				}
			}
        	
        });
    }

	/* (non-Javadoc)
	 * @see android.app.Activity#onResume()
	 */
	@Override
	protected void onResume() {
		super.onResume();

		(new Timer(false)).schedule(new AnimationTimer(earthButtonAnimation), 100);
	}

	/* (non-Javadoc)
	 * @see android.app.Activity#onPause()
	 */
	@Override
	protected void onPause() {
		super.onPause();
		earthButtonAnimation.stop();
	}

	private static class AnimationTimer extends TimerTask {
		AnimationDrawable animation;
		
		public AnimationTimer(AnimationDrawable animation) {
			this.animation = animation;
		}

		@Override
		public void run() {
			animation.start();
			this.cancel();
		}
		
	}
    
}

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent" android:id="@+id/frame_layout"
	android:background="@drawable/space_background">

	<Button android:id="@+id/earth_button" android:background="@anim/earth_animation"
		android:text="@string/click_me_to_stop" android:layout_gravity="center"
		android:text android:textColor="#ff9900"
		android:layout_marginBottom="12dip" android:layout_marginRight="12dip"
		android:layout_marginTop="12dip" android:maxHeight="296dip"

		android:layout_width="wrap_content" android:width="296dip"
		android:height="296dip" android:layout_marginLeft="-10dip"

</FrameLayout>

上面主vxml

下面是地球的正反旋转
