我的活动中有9个按钮，我使用右推动画在Create上显示我的按钮，我改变持续时间来设置显示，所以我有9个animation.xml，持续时间不同（从1000到5000）。< / p>
我也必须在活动中重复3行代码，
final Button b = (Button)findViewById(R.id.Button06);
Animation anim=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in);
b.startAnimation(anim);
所以，我需要知道是否有更简单的方法用更少的代码制作类似的东西？ 例如，使用1 animation.xml并定义按钮一个接一个地运行动画？！
我的完整代码：
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.Button;
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button b = (Button)findViewById(R.id.Button06);
Animation anim=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in);
b.startAnimation(anim);
final Button b1 = (Button)findViewById(R.id.Button03);
Animation anim1=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in1);
b1.startAnimation(anim1);
final Button b2 = (Button)findViewById(R.id.button1);
Animation anim2=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in2);
b2.startAnimation(anim2);
final Button b3 = (Button)findViewById(R.id.Button08);
Animation anim3=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in3);
b3.startAnimation(anim3);
final Button b4 = (Button)findViewById(R.id.Button04);
Animation anim4=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in4);
b4.startAnimation(anim4);
final Button b5 = (Button)findViewById(R.id.Button01);
Animation anim5=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in5);
b5.startAnimation(anim5);
final Button b6 = (Button)findViewById(R.id.Button07);
Animation anim6=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in6);
b6.startAnimation(anim6);
final Button b7 = (Button)findViewById(R.id.Button05);
Animation anim7=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in7);
b7.startAnimation(anim7);
final Button b8 = (Button)findViewById(R.id.Button02);
Animation anim8=AnimationUtils.loadAnimation(MainActivity.this, R.anim.push_right_in8);
b8.startAnimation(anim8);
b.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
startButtonAnimation(b);
}
});
}
public void startButtonAnimation(Button btn){
Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
btn.setAnimation(shake);
btn.startAnimation(shake);
shake.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
startActivity(new Intent(getApplicationContext(), Activity2.class));
overridePendingTransition(R.anim.animation, R.anim.animation2);
}
});
}
@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;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
答案 0 :(得分：3)
是的，你可以创建方法
private void buttonAnim(int buttonId, long duration){
Button b = (Button) findViewById(buttonId);
Animation anim=AnimationUtils.loadAnimation(MainActivity.this,your_anim_id);
anim.setDuration(duration);
b.startAnimation(anim);
}
并使用它来调用你的动画：
buttonAnim(R.anim.Button06, 1000);
此外，您可以将按钮放在数组中并按循环执行，如下面的代码所示：
int[] buttonsArrays = new int {
R.anim.Button01,
R.anim.Button02,
R.anim.Button06,
...
}
int[] durations = new int {
1000,
5000,
1000,
...
}
在您的代码中：
for(int index=0; index <buttonsArrays.length; index++){
buttonAnim(buttonsArrays[index],durations[index]);
}
但请记住，数组的长度必须相同
或者您可以使用Pair对象，如下面的代码所示：
Pair<Integer, Long>[] pairs = new Pair[]{
new Pair(R.id.Button01, 1000l),
new Pair(R.id.Button02, 5000l),
...
};
在您的代码中：
for(Pair<Integer,Long> pair : pairs ){
buttonAnim(pair.first,pair.second);
}
这将是最节省的
修改
请找到我的班级命题：

new ButtonSupport(R.id.Button06,1000l, YourClassActivity.class),
