Android的四個動畫特效
Android的四個動畫分別是漸變透明,縮放尺寸,旋轉角度,移動方向等動畫組合,這些動畫可以在res資原始檔下中新建的anim資料夾下建立一些常用的動畫屬性檔案供自己呼叫。下面筆者用寫程式碼來說明四個動畫的執行效果,並動態的設定動畫各個引數屬性值,方便一些學習者測試,並窺視它的動畫細節,以便以掌握動畫特效。寫純程式碼實現動畫還能方便開發者打包jar.
特別宣告,請讀者務必具備一定的英語閱讀能力。
一,漸變動畫alpha
建立一個繼承Activity的漸變動畫頁面類AlphaActivity.java
public class AlphaActivity extends Activity { private ImageView spaceshipImage; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.activity_alpha); spaceshipImage = (ImageView) this.findViewById(R.id.imageView_alpha); ((Button) this.findViewById(R.id.button_start_alpha)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startAlpha(); } }); } /** * Alpha漸變動畫,從透明到不透明,範圍值為百分比 */ private void startAlpha() { // 設定動畫開始時的透明度 String text = ((EditText) this.findViewById(R.id.editText_from_alpha)).getText().toString(); if(text.equals("")) text = "0.1"; float fromAlpha = Float.valueOf(text); // 設定動畫結束時的透明度 text = ((EditText) this.findViewById(R.id.editText_to_alpha)).getText().toString(); if(text.equals("")) text = "1.0"; float toAlpha = Float.valueOf(text); // 設定動畫時間 text = ((EditText) this.findViewById(R.id.editText_duration_alpha)).getText().toString(); if(text.equals("")) text = "1000"; int duration = Integer.valueOf(text); Animation alphaAnimation = new AlphaAnimation(fromAlpha, toAlpha); alphaAnimation.setDuration(duration); // 開始動畫 this.spaceshipImage.startAnimation(alphaAnimation); } }

二,縮放動畫scale
建立一個繼承Activity的縮放動畫介面類ScaleActivity.java
public class ScaleActivity extends Activity { private ImageView spaceshipImage; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setContentView(R.layout.activity_scale); spaceshipImage = (ImageView) this.findViewById(R.id.imageView_scale); ((Button) this.findViewById(R.id.button_start_scale)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startScale(); } }); } private void startScale() { String text = ((EditText) this.findViewById(R.id.editText_fromx_scale)).getText().toString(); if(text.equals("")) text = "0.1"; float from_x_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_tox_scale)).getText().toString(); if(text.equals("")) text = "1.0"; float to_x_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_fromy_scale)).getText().toString(); if(text.equals("")) text = "0.1"; float from_y_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_toy_scale)).getText().toString(); if(text.equals("")) text = "1.0"; float to_y_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_pivotX_scale)).getText().toString(); if(text.equals("")) text = "0"; float pivotX_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_pivotY_scale)).getText().toString(); if(text.equals("")) text = "0"; float pivotY_scale = Float.valueOf(text); text = ((EditText) this.findViewById(R.id.editText_duration_scale)).getText().toString(); if(text.equals("")) text = "1000"; int duration = Integer.valueOf(text); // Animation scaleAnimation = new ScaleAnimation(from_x_scale, to_x_scale, from_y_scale, to_y_scale); // 另外還可以設定伸縮模式pivotXType、pivotYType, 伸縮動畫相對於x,y 座標的開始位置pivotXValue、pivotYValue等。 Animation scaleAnimation = new ScaleAnimation(from_x_scale, to_x_scale, from_y_scale, to_y_scale, Animation.RELATIVE_TO_SELF, pivotX_scale, Animation.RELATIVE_TO_SELF, pivotY_scale); // scaleAnimation.setRepeatCount(repeatCount) scaleAnimation.setDuration(duration); this.spaceshipImage.startAnimation(scaleAnimation); } }

建立一個繼承Activity的旋轉動畫介面類RotateActivity.java
public class RotateActivity extends Activity {
private ImageView spaceshipImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_rotate);
spaceshipImage = (ImageView) this.findViewById(R.id.imageView_rotate);
((Button) this.findViewById(R.id.button_start_rotate)).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
startScale();
}
});
}
private void startScale() {
String text = ((EditText) this.findViewById(R.id.editText_start_rotate)).getText().toString();
if(text.equals("")) text = "0";
float start_degree_rotate = Float.valueOf(text);
text = ((EditText) this.findViewById(R.id.editText_end_rotate)).getText().toString();
if(text.equals("")) text = "360";
float end_degree_rotate = Float.valueOf(text);
text = ((EditText) this.findViewById(R.id.editText_pivotX_rotate)).getText().toString();

float pivotX_rotate = Float.valueOf(text);
text = ((EditText) this.findViewById(R.id.editText_pivotY_rotate)).getText().toString();
if(text.equals("")) text = "0";
float pivotY_rotate = Float.valueOf(text);
text = ((EditText) this.findViewById(R.id.editText_duration_rotate)).getText().toString();
if(text.equals("")) text = "1000";
int duration = Integer.valueOf(text);
// Animation rotateAnimation = new RotateAnimation(start_degree_rotate, end_degree_rotate);
// 另外還可以設定伸縮模式pivotXType、pivotYType, 伸縮動畫相對於x,y 座標的開始位置pivotXValue、pivotYValue等。
Animation rotateAnimation = new RotateAnimation(start_degree_rotate, end_degree_rotate,
Animation.RELATIVE_TO_SELF, pivotX_rotate, Animation.RELATIVE_TO_SELF, pivotY_rotate);
rotateAnimation.setDuration(duration);
this.spaceshipImage.startAnimation(rotateAnimation);

建立一個繼承Activity的位移動畫介面類TranslateActivity.java
public class TranslateActivity extends Activity {

// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_translate);

五,多頁卡的主頁面
建立一個有四個選項卡的頁卡主頁面MainActivity.java,繼承與TabActivity
public class MainActivity extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 漸變動畫一
TabHost tabHost = this.getTabHost();
TabSpec tab1 = tabHost.newTabSpec("tab1");
tab1.setIndicator("漸變");
tab1.setContent(new Intent(this, AlphaActivity.class));
tabHost.addTab(tab1);
// 縮放動畫二
TabSpec tab2 = tabHost.newTabSpec("tab2");
tab2.setIndicator("縮放");
tab2.setContent(new Intent(this, ScaleActivity.class));
tabHost.addTab(tab2);
// 旋轉動畫三
TabSpec tab3 = tabHost.newTabSpec("tab3");
tab3.setIndicator("旋轉");
tab3.setContent(new Intent(this, RotateActivity.class));
tabHost.addTab(tab3);
// 位移動畫四
TabSpec tab4 = tabHost.newTabSpec("tab4");
tab4.setIndicator("位移");
tab4.setContent(new Intent(this, TranslateActivity.class));
tabHost.addTab(tab4);
}
}
下面是主頁面的main的佈局檔案activity_main.xml,其中tabHost,tabWidget元件id為自動設定不能修改
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<TabHost
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" >
</FrameLayout>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TabWidget>
</LinearLayout>
</TabHost>
</RelativeLayout>
六,在AndrroidManifest.xml屬性檔案中新增上面的四個繼承與Activity類的屬性
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.animationtest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.animationtest.MainActivity"
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="AlphaActivity"></activity>
<activity android:name="ScaleActivity"></activity>
<activity android:name="RotateActivity"></activity>
<activity android:name="TranslateActivity"></activity>
</application>
</manifest>
七,專案總算完成了,專案沒有報錯的話那安裝在模擬器中,執行介面按下開始動畫按鈕測試效果看看吧。
