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
