我的应用包含许多活动。当用户午餐时，应用程序显示包含带按钮的表的主要活动。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，用户将按下按钮以执行两个功能： 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以实现两个功能： 1-向主活动发送两个字符串变量和一个int（用于在表中显示）。 2-午餐主要活动。
我的问题是，三个变量中有一个（它是新手）在桌面上显示出来。我尝试过使用Intent或Bundle发送的方式。
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);
}});
所有按钮都相同
用户在将数据发送到主活动后对数据进行编辑的活动 在这里接收：
Intent n = this.getIntent();
nam =n.getExtras().getString("meal");
con = n.getExtras().getString("con");
cal =n.getExtras().getInt("cal");
这里编辑：

答案 0 :(得分：1)
似乎dlopen失败了： 如果您要dlopen的库不在标准搜索路径中，则您有许多选项：
在dlopen中指定文件的完整路径
的dlopen（＆＃34; /full/path/to/libfile.so"）; 通过LD_LIBRARY_PATH
添加到库的路径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＆amp; 3将库路径硬编码到您的应用程序中。 -rpath可以选择指定相对路径，即
-Wl，-rpath = $ ORIGIN /../ LIB / 将嵌入相对路径的应用程序。
试试吧。
