在如登錄界面上當輸入框獲得焦點時，爲了將輸入框顯示出來，不被軟鍵盤遮住，我們可以監聽軟鍵盤的顯示與關閉來實現

首先在build.gradle中配置依賴

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

佈局是一個圖片和一個輸入框
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();
    }
    // 實現未實現的方法
    @Override
    public void onKeyboardShown(int keyboardSize) {
        img.setVisibility(View.GONE);
    }
    // 實現未實現的方法
    @Override
    public void onKeyboardClosed() {
        img.setVisibility(View.VISIBLE);
    }
    // 初始化軟鍵盤監聽
    private void initKeyWatch() {
        mKeyboardWatcher = new KeyboardWatcher(this);
        mKeyboardWatcher.setListener(this);
    }
}

然後在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>

如果沒有在AndroidManifest.xml裏做相應配置，會報如下錯誤
Caused by: java.lang.IllegalArgumentException: Activity MainActivity should have windowSoftInputMode=”adjustResize”to make KeyboardWatcher working. You can set it in AndroidManifest.xml
