Activity Will Get Get Destroyed and Turn Back To Main Activity Error: E/AndroidRuntime: FATAL EXCEPTION: main

Question

所以我一直在寻找 Whosebug + reddit + 文档，但仍然没有解决这个问题，我尝试了很多 catch 块，但没有任何线索我尝试了 bytearray 但仍然是同样的问题。这是错误：

ERROR """  E/AndroidRuntime: FATAL EXCEPTION: main

''' **代码： ''' 试试{

                    }
                });


                decode.setOnClickListener(new View.OnClickListener() {
                    @Override

                        decode.setText(new String(Base64.decode(inputText.getText().toString(), Base64.DEFAULT)));

                    }
                });

            }
           
            catch (Exception e) {

            }        ''''code** '''

UPDATE::::: 虽然测试编码部分很好，但有时解码会完全脱离 class/activity 并到达主要部分并向我显示代码上方的错误::: : 更新

如果您有任何解决方案或之前遇到过此问题，请lmk。提前致谢

问题出在您的 try/catch 块的结构中。你有一个形状像这样的东西：

try {
    encode.setOnClickListener(...);
    decode.setOnClickListener(...);
} catch (Exception e) {
    // ...
}

这只会捕获设置侦听器时抛出的异常。它不会对从侦听器内部抛出的异常产生任何影响。

试试这个：

decode.setOnClickListener(
    @Override
    public void onClick(View v) {
        try {
            decode.setText(...);
        } catch (Exception e) {
            // show toast message here
        }
    }
);
