我无法让我的应用运行！它没有编译错误，安装完美。但是，当我单击自定义按钮时，应用程序将停止。我复制了整个java和xml文件并使用一个TextView进行了一个简单的活动，并且它有效。它进入活动并显示TextView。这是java，xml和logcat代码：

package l.pocketformulas;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;


public class Formulas extends Activity {

Button bAlgebra, bTrigonometry, bCalculus, bGeometry;


@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    // FULL SCREEN & HIDE APP TITLE
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.formulas);

    initVars();

    bAlgebra.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent algebraInt = new Intent("android.intent.action.ALGEBRA");
            startActivity(algebraInt);
        }
    });
    bTrigonometry.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent trigonometryInt = new Intent(
                    "android.intent.action.TRIGONOMETRY");
            startActivity(trigonometryInt);
        }
    });
    bGeometry.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent geometryInt = new Intent(
                    "android.intent.action.GEOMETRY");
            startActivity(geometryInt);
        }
    });
    bCalculus.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent calculusInt = new Intent(
                    "android.intent.action.CALCULUS");
            startActivity(calculusInt);
        }
    });

}

private void initVars() {
    // TODO Auto-generated method stub
    bAlgebra = (Button) findViewById(R.id.bAlgebra);
    bTrigonometry = (Button) findViewById(R.id.bTrigonometry);
    bCalculus = (Button) findViewById(R.id.bCalculus);
    bGeometry = (Button) findViewById(R.id.bGeometry);
}
}
