java.lang.StackOverFlowError 在 android 工作室

Question

我是新 android 应用程序的初学者，我已根据教程完成所有操作，但我仍然遇到此错误。这是 MyAcitivty.java:

的代码

这是MYActivity.java

 package com.example.ambuj.myfirstapp;

 import android.content.Intent;
 import android.support.v7.app.ActionBarActivity;
 import android.os.Bundle; 
 import android.view.Menu; 
 import android.view.MenuInflater;
 import android.view.MenuItem;
 import android.view.View;
 import android.widget.EditText;
 import android.widget.Toast;


 public class MyActivity extends ActionBarActivity {

public final static String EXTRA_MESSAGE = "com.example.ambuj.myfirstapp";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);


}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
     MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main_activity_actions, menu);
    return onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
        switch (item.getItemId()) {
            case R.id.action_search:
                openSearch();
                return true;
            case R.id.action_settings:
                openSettings();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }

    }




public void sendMessage(View view){
    Intent intent = new Intent(this, DisplayMessageActivity.class);
    EditText editText = (EditText) findViewById(R.id.edit_message);
    String message = editText.getText().toString();
    intent.putExtra(EXTRA_MESSAGE, message);
    startActivity(intent);

}

public void openSearch(){
    Toast.makeText(this, "Search Button Pressed", Toast.LENGTH_LONG).show();
}

public void openSettings(){
    Toast.makeText(this, "Settings Button Pressed",Toast.LENGTH_LONG).show();
}

}

这是我的 logcat:

Answer 1

你的问题在这里：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
 MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return onCreateOptionsMenu(menu); //<--- conflicting line
}

改变

return onCreateOptionsMenu(menu);

到

return true;
