設置窗口標題事件和在Activity之間跳轉。
新建一個項目，新建兩個Activity:MainActivity,TitleActivity ,然后再AnroidManifest.xml 中注冊TitleActivity
AndroidManifest.xml內容如下
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.neil.ad02"><applicationandroid:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme"><activity android:name=".MainActivity"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity><activity android:name=".TitleActivity"android:label="@string/app_name"></activity></application></manifest>
在MainActivity中的onCreate方法中
@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Log.d("onCreate","onCreate Method is executed");Button bt=(Button)findViewById(R.id.btTurnTitle);bt.setOnClickListener(new View.OnClickListener() {public void onClick(View v) {startActivity(new Intent(MainActivity.this,TitleActivity.class));}});}點擊Button就觸發TitleActivity的onCreate()->onStart()->onResume()方法
向activity_title.xml中添加一個Button，點擊Button就改變app_name的值
TitleActivity中的代碼
package com.neil.ad;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;/*** Created by Neil on //.*/public class TitleActivity extends Activity{@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_title);Button bt=(Button)findViewById(R.id.btTitle);bt.setOnClickListener((View.OnClickListener) this);setTitle("窗口標題");}public void onClick_SetTitle(View view){setTitle("新窗口標題");setTitleColor();}//在窗口完全開始后調用該方法@Overrideprotected void onPostCreate(Bundle savedInstanceState) {Log.d("TitleActivity","onPostCreate");super.onPostCreate(savedInstanceState);}@Overrideprotected void onTitleChanged(CharSequence title,int color){super.onTitleChanged(title,color);Log.d("TitleActivity","onTitleChanged_title"+title);Log.d("TitleActivity","onTitleChanged_color"+color);}}比較簡單，就不多說了。如果大家有任何疑問歡迎給我留言，小編會及時回復大家的！
