Android开发之旅一简单的Animator动画使用
对于Path的菜单效果看着很不错，今天就使用动画做个没有幅度的试试？
练练手重写RelativeLayout
看主布局
MainActivity
package com.example.testpath;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TestLayout layout=(TestLayout) findViewById(R.id.layout);
List imgRes=new ArrayList();
imgRes.add(R.drawable.composer_music);
imgRes.add(R.drawable.composer_music);
imgRes.add(R.drawable.composer_music);
imgRes.add(R.drawable.composer_music);
imgRes.add(R.drawable.composer_music);
layout.init(R.drawable.composer_music, imgRes, TestLayout.LEFT_BOTTOM);
layout.setOnPKButClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
System.out.println("----getId-----"+v.getId());
}
});
/* layout.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent event) {
// TODO Auto-generated method stub
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
System.out.println("----dd------");
return false;
case MotionEvent.ACTION_MOVE:
System.out.println("----mm------");
return false;
case MotionEvent.ACTION_UP:
System.out.println("----uu------");
return false;
}
return false;
}
});*/
}
@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);
}
}
