E/AndroidRuntime:致命异常：main java.lang.IllegalStateException:无法为android执行方法：onClick

当只创建一个按钮时，一切正常，但每当我为不同的按钮创建一个方法时，就会出现以下错误：

E/AndroidRuntime: FATAL EXCEPTION: main java.lang.IllegalStateException: Could not execute method for android:onClick   Caused by: java.lang.reflect.InvocationTargetException   Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x0

请帮忙

我认为真正的错误是在中间，行<代码> Android .Cyt.RES.RealsNoBuffDestExpTest:EngultID.0x0在暗示它找不到您通过的资源。

您传入的资源通常类似于

R.raw.my\u resource\u name

---

更多信息和。

问题是在以下代码中找不到有效的资源ID：

public void pressed(View view) {

    int id = view.getId();
    String ourId = "";

    ourId = view.getResources().getResourceEntryName(id);

    int resourceId = getResources().getIdentifier(ourId, "raw", 
    "com.example.chakshu.griddemo");

    ...
}

public void pressed(View view) {

  String resName = (String) view.getTag();
  int resId = getResources().getIdentifier(resName, "raw", getPackageName());

  if(resId == 0) {
     Log.d("MainActivity", "error, no found raw");
  } else {
     MediaPlayer mplayer = MediaPlayer.create(this, resourceId);
     mplayer.start();
  }
}

其中将抛出

Resources.NotFoundException

，因为该id不存在，如果找不到有效的资源id，将返回0

因此，将您的click listener方法更新为如下内容：

public void pressed(View view) {

    int id = view.getId();

    try {
      String ourId = getResources().getResourceEntryName(id);
      int resId = getResources().getIdentifier(ourId, "raw", getPackageName());

      if(resId == 0) {
        Log.d("MainActivity", "error, no found raw");
      } else {
        MediaPlayer mplayer = MediaPlayer.create(this, resourceId);
        mplayer.start();
      }
    } catch(NotFoundException e) {
      Log.d("MainActivity", "error, no found resource = " + e.toString);
    }


}

根据按钮ID名称，尝试使用

android:tag

和

[getTag][3]

方法。例如，使用以下按钮：

<Button
    android:text="A"
    android:tag="raw_resource_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/button"
    android:layout_column="0"
    android:layout_row="0"
    android:layout_gravity="fill"
    android:layout_columnWeight="1"
    android:layout_rowWeight="1"
    android:onClick="pressed"/>

R.raw.value

只是一个整数。代码试图使用getResources（）@cricket\u 007动态构建该值是的，我知道。显然，它找不到资源，但是如果看不到XML或资源，很难说还有什么其他的，或者知道动态构建它与只使用整数相比，是否有特定的原因。当然。我认为主要的问题是，点击的视图id很少（如果有的话）与原始资源id匹配。请将您的相关代码添加到问题中。添加了先生。请提供帮助

public void pressed(View view) {

  String resName = (String) view.getTag();
  int resId = getResources().getIdentifier(resName, "raw", getPackageName());

  if(resId == 0) {
     Log.d("MainActivity", "error, no found raw");
  } else {
     MediaPlayer mplayer = MediaPlayer.create(this, resourceId);
     mplayer.start();
  }
}
