Android 按钮不执行其编程的操作

我有两个if语句，其中if

modechoiceId == R.id.textmode && sizechoiceId == R.id.normal -- 1

或

（1）将使下一个按钮转到一个新的活动，即textmode32by32.class和 （2）将使下一个按钮转到一个新活动，即animationmode32by32.class

现在的问题是，这两个选项将转到同一个页面，即textmode32by32.class

问题是否出在放射组？或者代码在if语句中

                    && sizechoiceId == R.id.normal) {

                //first
            } else if (modechoiceId == R.id.animationmode
                    && sizechoiceId == R.id.normal) {

                //second activity
            }

        }
    });

问题是，当

startPage

活动启动时，它会将按钮侦听器onclick直接设置为

if（modechoiceId==R.id.textmode&&sizechoiceId==R.id.normal）

为什么？

因为每次选中另一个单选按钮时，您不会更改它

解决方案：

if(modechoiceId == R.id.textmode && sizechoiceId == R.id.normal){

        nextButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent nextSelection = new Intent(startPage.this, textmode32by32.class);
                startActivity(nextSelection);

            }
        });

    }

    else if(modechoiceId == R.id.animationmode && sizechoiceId == R.id.normal){

        nextButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent nextSelection1 = new Intent(startPage.this, animationmode32by32.class);
                startActivity(nextSelection1);

            }
        });

    }

 nextButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                int modechoiceId = modeselection.getCheckedRadioButtonId();
                int sizechoiceId = sizeselection.getCheckedRadioButtonId();

                if(modechoiceId == R.id.textmode && sizechoiceId == R.id.normal){

                   Intent nextSelection1 = new Intent(startPage.this, animationmode32by32.class);
                   startActivity(nextSelection1);

        }

                else if(modechoiceId == R.id.animationmode && sizechoiceId == R.id.normal){

                    Intent backSelection = new Intent(startPage.this, MainActivity.class);
            startActivity(backSelection);
}
                }
            });

将检查单选按钮置于onclick侦听器中

更改此选项：

if(modechoiceId == R.id.textmode && sizechoiceId == R.id.normal){

        nextButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent nextSelection = new Intent(startPage.this, textmode32by32.class);
                startActivity(nextSelection);

            }
        });

    }

    else if(modechoiceId == R.id.animationmode && sizechoiceId == R.id.normal){

        nextButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent nextSelection1 = new Intent(startPage.this, animationmode32by32.class);
                startActivity(nextSelection1);

            }
        });

    }

 nextButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                int modechoiceId = modeselection.getCheckedRadioButtonId();
                int sizechoiceId = sizeselection.getCheckedRadioButtonId();

                if(modechoiceId == R.id.textmode && sizechoiceId == R.id.normal){

                   Intent nextSelection1 = new Intent(startPage.this, animationmode32by32.class);
                   startActivity(nextSelection1);

        }

                else if(modechoiceId == R.id.animationmode && sizechoiceId == R.id.normal){

                    Intent backSelection = new Intent(startPage.this, MainActivity.class);
            startActivity(backSelection);
}
                }
            });

至：

if(modechoiceId == R.id.textmode && sizechoiceId == R.id.normal){

        nextButton.setOnClickListener(new View.OnClickListener() {

            @Override
