setText() 或 Intent 不起作用答案

【问题标题】：setText() or Intent doesn't worksetText() 或 Intent 不起作用
【发布时间】：2016-11-23 06:27:10
【问题描述】：

我的应用程序包含许多活动。当用户午餐时，应用程序显示包含一个带有按钮的表格的主要活动。如果用户按下其中一个按钮，应用程序将转到另一个活动，每个按钮代表活动。在其中一个活动中，用户将按下按钮执行两个功能： 1-发送两个字符串变量和一个 int 。 2-午餐另一项活动。在活动中，用户将编辑数据，之后用户将按下按钮执行两个功能： 1-将两个字符串变量和一个 int 发送到主要活动（用于在表格中显示）。 2- 午餐主要活动。

我的问题是，三分之一的变量（它是 newkindm）已显示在桌面上。我尝试使用多种方式通过 Intent 或 Bundle 发送。

主要活动

         condi_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, CONDIMENT.class);
            startActivity(q);
            finish();
        }
    });

    egg_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, EGG.class);
            startActivity(q);
            finish();
        }
    });

    fast_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, FAST.class);
            startActivity(q);
            finish();
        }
    });

    fish_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, FISH_CHECKEN.class);
            startActivity(q);
            finish();
        }
    });

    fruit_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, FRUIT.class);
            startActivity(q);
            finish();
        }
    });

    meat_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, MEAT.class);
            startActivity(q);
            finish();
        }
    });

    milk_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, MILK.class);
            startActivity(q);
            finish();
        }
    });

    mooca_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, MOOCA.class);
            startActivity(q);
            finish();
        }
    });

    oil_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, OIL_FAT.class);
            startActivity(q);
            finish();
        }
    });

    rice_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, RICE_BREAD.class);
            startActivity(q);
            finish();
        }
    });

    vege_button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent q = new Intent(MainActivity.this, VEGETABLE.class);
            startActivity(q);
            finish();
        }
    });

众多活动之一：

 fas001add.setOnClickListener(new OnClickListener (){

        @Override
        public void onClick(View v) {
            Intent a = new Intent(FAST.this,Add.class);
            a.putExtra("cal", Content.Fast001.calory);
            a.putExtra("con", Content.Fast001.consist);
            a.putExtra("meal", Content.Fast001.meal);
            startActivity(a);


        }});

所有按钮都一样

用户在数据上编辑的活动，然后将其发送到主活动这里接收：

    Intent n = this.getIntent();
    nam =n.getExtras().getString("meal");
    con = n.getExtras().getString("con");
    cal =n.getExtras().getInt("cal");

这里编辑：

错误 logcat error only

【问题讨论】：

发布您的错误，发布您的LogCat，并改进格式代码。
@Aspicas 我上传 logcat.txt 你有什么推荐的？
文件无法正常显示错误日志

标签： android android-studio android-intent

【解决方案1】：

似乎 dlopen failed 之类的错误：如果您要 dlopen 的库不在标准搜索路径中，您有多种选择：

在 dlopen 中指定文件的完整路径

dlopen("/full/path/to/libfile.so"); 通过 LD_LIBRARY_PATH 添加库的路径

LD_LIBRARY_PATH=/path/to/library/./executable 使用 ld -rpath 选项将库路径添加到应用程序。

g++ -link stuff- -Wl,-rpath=/path/to/library/ 请注意，选项 1 和 3 将库路径硬编码到您的应用程序中。 -rpath 确实有一个选项来指定相对路径，即

-Wl,-rpath=$ORIGIN/../lib/ 将在应用程序中嵌入相对路径。

试试看。
