Android之UI学习篇三：TextVeiw单击文字链接弹出Activity

在TextView中还可以实现单击文字，来跳转到设定的Activity中去，是不是很神奇呀，

先看看实现的效果:

MainActivity界面截图：

单击"显示Activity1"之后，弹出Activity1的窗口，截图如下：

同样，单击"显示Activity2"弹出界面截图：

实现代码如下：

由于main.xml文件比较简单，这里就不给出源代码了哦，

MainActivity.java

publicclassAndroid_TextviewActivityextendsActivity{privateTextViewtextView1;privateTextViewtextView2;@OverridepublicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.main);/**TextView中实现Activity的跳转**/textView1=(TextView)findViewById(R.id.textview1);textView2=(TextView)findViewById(R.id.textview2);Stringtext1="显示Activity1";Stringtext2="显示Activity2";SpannableStringspannableString1=newSpannableString(text1);spannableString1.setSpan(newClickableSpan(){@OverridepublicvoidonClick(Viewview){Intentintent=newIntent(Android_TextviewActivity.this,Activity1.class);startActivity(intent);}},0,text1.length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);SpannableStringspannableString2=newSpannableString(text2);spannableString2.setSpan(newClickableSpan(){@OverridepublicvoidonClick(Viewview){Intentintent=newIntent(Android_TextviewActivity.this,Activity2.class);startActivity(intent);}},0,text2.length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);textView1.setText(spannableString1);textView1.setMovementMethod(LinkMovementMethod.getInstance());textView2.setText(spannableString2);textView2.setMovementMethod(LinkMovementMethod.getInstance());}}

Activity1.java

packagecom.android.mytextview;importandroid.app.Activity;importandroid.os.Bundle;importandroid.widget.TextView;publicclassActivity1extendsActivity{@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setTitle("Activity1");TextViewtextView=newTextView(Activity1.this);textView.setText("这里是Activity1的地盘");setContentView(textView);}}

Activity2.java

packagecom.android.mytextview;importandroid.app.Activity;importandroid.os.Bundle;importandroid.widget.TextView;publicclassActivity2extendsActivity{@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setTitle("Activity2");TextViewtextView=newTextView(Activity2.this);textView.setText("这里是Activity2的地盘");setContentView(textView);}}
