在如登录界面上当输入框获得焦点时，为了将输入框显示出来，不被软键盘遮住，我们可以监听软键盘的显示与关闭来实现

首先在build.gradle中配置依赖

compile 'com.azimolabs.keyboardwatcher:keyboardwatcher:0.1.3'

布局是一个图片和一个输入框
MainActivity.java

package cn.wuxiaocheng.keyboardwatcher;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import com.azimolabs.keyboardwatcher.KeyboardWatcher;
public class MainActivity extends AppCompatActivity implements KeyboardWatcher.OnKeyboardToggleListener 
    private ImageView img;
    private KeyboardWatcher mKeyboardWatcher;
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        img = (ImageView) findViewById(R.id.img);
        initKeyWatch();
    
    // 实现未实现的方法
    @Override
    public void onKeyboardShown(int keyboardSize) 
        img.setVisibility(View.GONE);
    
    // 实现未实现的方法
    @Override
    public void onKeyboardClosed() 
        img.setVisibility(View.VISIBLE);
    
    // 初始化软键盘监听
    private void initKeyWatch() 
        mKeyboardWatcher = new KeyboardWatcher(this);
        mKeyboardWatcher.setListener(this);
    

然后在AndroidManifest.xml中添加android:windowSoftInputMode=”“配置

<activity android:name=".MainActivity"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

如果没有在AndroidManifest.xml里做相应配置，会报如下错误
Caused by: java.lang.IllegalArgumentException: Activity MainActivity should have windowSoftInputMode=”adjustResize”to make KeyboardWatcher working. You can set it in AndroidManifest.xml
