點擊textvie跳轉到activity
這裏使用到SpannableString類，主要用於在指定的字符串點擊觸發的事件（具體實現代碼如下） 在manifest.xml中添加兩個activtity
tv1.setMovementMethod(LinkMovementMethod.getInstance()); 添加鏈接
<activity android:name=".Activity1"></activity> <activity android:name=".Activity2"></activity>
package com.android.textview1;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.SpannedString;
import android.text.method.LinkMovementMethod;
import android.text.style.ClickableSpan;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv1 = (TextView) this.findViewById(R.id.textview1);
TextView tv2 = (TextView) this.findViewById(R.id.textview2);
String text1 = "跳轉到Activity1";
String text2 = "跳轉到Activity2";
// spannableString用於拆分字符串
SpannableString spannedString1 = new SpannableString(text1);
SpannableString spannedString2 = new SpannableString(text2);
spannedString1.setSpan(new ClickableSpan() {
// 點擊0到text.length觸發事件
@Override
public void onClick(View widget) {
// 創建一個界面跳轉的意圖
Intent intent = new Intent(MainActivity.this, Activity1.class);
// 啓動意圖
startActivity(intent);
}
}, 0, text1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spannedString2.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this, Activity2.class);
startActivity(intent);
}
}, 0, text2.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv1.setText(spannedString1);
tv2.setText(spannedString2);
// 設置連接
tv1.setMovementMethod(LinkMovementMethod.getInstance());
tv2.setMovementMethod(LinkMovementMethod.getInstance());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
