我的布局中有两个按钮，

buttonAddImage
buttonLoadImage

现在我需要的是，我想启用＆＃34; buttonLoadImage＆＃34;如果用户onclick＆＃34; buttonAddImage＆＃34; else＆＃34; buttonLoadImage＆＃34;总是禁用。如何帮助我。

        final Button buttonAddImage = (Button)   findViewById(R.id.buttonAddPicture);
        final Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
        buttonAddImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            buttonLoadImage.setEnabled(true);
            Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            // Start the Intent
            startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);

        }

    });

Answer 1

在onClick方法

之外添加禁用按钮的代码

        final Button buttonAddImage = (Button) findViewById(R.id.buttonAddPicture);
        final Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
        buttonLoadImage.setEnabled(false);
        buttonAddImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            buttonLoadImage.setEnabled(true);
            Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            // Start the Intent
            startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);

        }

    });

Answer 2

尝试在buttonAddImage

的onclick中设置buttonLoadImage的监听器

 @Override
    public void onClick(View view) {
        buttonLoadImage.setOnClickListener(this);
        Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        // Start the Intent
        startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);

    }

使用此

final Button buttonAddImage = (Button) findViewById(R.id.buttonAddPicture);
final Button buttonLoadImage = (Button)findViewById(R.id.buttonLoadPicture);
buttonLoadImage.setEnabled(false);
buttonAddImage.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
    buttonLoadImage.setEnabled(true);
}

像你这样在你的班级中定义变量 private boolen ISCLICKED=false; d 然后

buttonAddImage.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View view) {

        Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        // Start the Intent
        startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);
       ISClLICKED=true

    }

});

现在点击检查按钮

    if(ISCLICKED==true){

buttonLoadImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {


            //do somththing

        }

    });
}else
{
Toast.maketext(contex,"Add image 1st",Toast.LENGHT_SHORT).show;
}

如何启用基于onclick的按钮在android中的另一个按钮？
