该博客介绍如何在Android中实现类似探探应用的侧滑效果。通过`DrawerLayout`和`ObjectAnimator`，动态调整内容视图的平移，模拟侧滑抽屉的打开和关闭动画。示例代码详细展示了如何设置监听器和动画效果。

package com.fanwf.inke.testdrawablelayout;

import android.animation.ObjectAnimator;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.TypedValue;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.RelativeLayout;

public class MainActivity extends AppCompatActivity {
    private DrawerLayout dl_layout;
    private RelativeLayout rl_content;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rl_content=(RelativeLayout)findViewById(R.id.rl_content);
        dl_layout= (DrawerLayout) findViewById(R.id.dl_layout);
        dl_layout.setScrimColor(getResources().getColor(R.color.traslateColor));
        dl_layout.setDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                int width= (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 300, getResources().getDisplayMetrics());
                ObjectAnimator animator=ObjectAnimator.ofFloat(rl_content,"translationX",drawerView.getId()==R.id.rl_right?-slideOffset*width:slideOffset*width);
                animator.setDuration(0);
                animator.start();
            }

            @Override
            public void onDrawerOpened(View drawerView) {

            }

            @Override
            public void onDrawerClosed(View drawerView) {

            }

            @Override
            public void onDrawerStateChanged(int newState) {

            }
        });
    }

}
