使用Snackbar之前，须导入com.android.support:design
使用示例
package com.bu_ish.snackbar_test;import android.graphics.Color;import android.support.design.widget.Snackbar;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Toast;public class SnackbarExampleActivity extends AppCompatActivity { private static final String TAG = SnackbarExampleActivity.class.getName(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_snackbar_example); findViewById(R.id.indefiniteButton).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Snackbar snackbar = Snackbar.make(v, "无限时长的Snackbar", Snackbar.LENGTH_INDEFINITE); snackbar.getView().setBackgroundColor(getResources().getColor(R.color.colorAccent)); snackbar.setActionTextColor(Color.WHITE); snackbar.setAction("关闭", new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(v.getContext(), "已关闭", Toast.LENGTH_SHORT).show(); } }); snackbar.addCallback(new Snackbar.Callback() { @Override public void onShown(Snackbar sb) { super.onShown(sb); Log.d(TAG, "Snackbar.Callback.onShown(Snackbar) called"); } @Override public void onDismissed(Snackbar transientBottomBar, int event) { super.onDismissed(transientBottomBar, event); Log.d(TAG, "Snackbar.Callback.onDismissed(Snackbar, int) called"); } }); snackbar.show(); } }); findViewById(R.id.longButton).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Snackbar snackbar = Snackbar.make(v, "长时效的Snackbar", Snackbar.LENGTH_LONG); snackbar.show(); } }); findViewById(R.id.shortButton).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Snackbar snackbar = Snackbar.make(v, "短时效的Snackbar", Snackbar.LENGTH_SHORT); snackbar.getView().setBackgroundColor(getResources().getColor(R.color.colorPrimary)); snackbar.show(); } }); }} 效果图
