개발 그리고 기억력 부족

In previous post  I made RecyclerView. In this post, I'll add name filtering ability to RecyclerView. First add EditText for user input. Use addTextChangedListener() for catch the change of EditText. Do DbTask asynchronously. This sample code is in GitHub.

RecyclerView is new in Android 5.0 (Lollipop) . To use with support library add compile 'com.android.support:recyclerview-v7:21.0.0' in build.gradle file dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:21.0.0' compile 'com.android.support:recyclerview-v7:21.0.0' } and import import android.support.v7.widget.RecyclerView; Get from layout xml RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycle_list); Plug in LayoutManager recyclerView.setLayoutManager(layoutManager); Create Adapter NameRecyclerAdapter mAdapter; ... mAdapter = new NameRecyclerAdapter(); Plug in Adapter recyclerView.setAdapter(mAdapter); NameRecyclerViewAdapter.java import android.database.Cursor; import android.support.v7.widget.RecyclerView; import android.view.ViewGroup; import android.widget.TextView; /** * * Recycler Adapter for TestDB
